Understand 10 JavaScript Concepts to Master coding

Every JavaScript developer should understand the basic concepts of this complex language.

The below concepts are not all, but these are the common foundational ones you need to know to take a step forward.

Let’s dive right in.


It stands for Immediately Invoked Function Expression. It’s the function that is called immediately after it’s created.

How can you define an IIFE? Look at the example below:

(() => console.log(‘Hello world’))();

As the code is executed, the console will log Hello world immediately.

The reason to use IIFE is to protect variables accessibility. The variables defined in IIFE can not be accessed from the outside. That’s the way to write maintainable code and prevent your source from becoming a mess.

2. MVC Structure

Not only in JavaScript, but this structure is used in almost programming languages. Far from the name MVC, it’s a popular concept to organize your code into different layers like data, view, and logic and treat them separately.

As a project going big, you need a structure to scale it up without putting your head to the wall. MVC is one of the best to follow in the first place for the long term plan. At some points in the future when adding new features or investigate bugs, you will thank yourself for spending time implementing MVC in the past.

3. Closure

We use this concept when talking about an inner function that always has access to the variables and parameters of its outer function, even after the outer function has returned.

Closure allows you to give accessibility to data inside a function without directly modifying them. This way, you can protect your code while giving others the ability to extend it. Especially when you public a library.

const sayHelloTo = name => {
  let message = ‘Hello ‘ + name;
  return () => console.log(message);
const sayHelloToAmy = sayHelloTo(‘Amy’);
sayHelloToAmy(); // Hello Amy

4. Async/await

Async/await allows you to work with asynchronous processing. You usually fall into asynchronous tasks when dealing with calling API. The data need to be fully fetched before showing up on the view.

What makes me satisfied with using async/await is I can get rid of callbacks hell. If you’re anything like me, you don’t like nested code. It makes your code ugly and less maintainable.

See the example below for async/await usage:

const displayData = async () => {
  const data = await fetch(‘');
  const jsonData = await data.json();

5. Scope

There are two types of scope in JavaScript. The local scope and the global one. You can imagine a variable scope is a cow tied to a post by a rope. It can only move in a limited area, depending on the length of the rope.

With that metaphor, the local variable is like a cow tied by a short rope and the global one is like a cow with no rope at all.

For example:

// Global scope
const globalCow = ‘global cow’;

const showCow = () => {
  const localCow = ‘local cow’;
  return globalCow;
const clonedCow = globalCow;
const mixedCow = globalCow + localCow; // error: Uncaught ReferenceError: localCow is not defined

As you can see, the variable globalCow can be used anywhere even in the local context of the function showCow. But you can’t use the variable localCow outside the function showCow since it’s defined locally.

6. Value vs Reference Types

When you assign values to variables, it’s not that simple to just assign the values. You need to understand whether it’s the actual values or references, otherwise, you probably change the values unintentionally.

The story is easy when you assign primitive types such as string, number, or boolean. They’re actual values.

A little bit more complex if you assign objects, arrays, or functions. This time, the variable won’t hold the actual value but the reference to the actual value in the memory.


let num1 = 1;
let num2 = num1;

// Changing num2’s value does not change num1’s value
num2 = 4;
console.log(num1); // 1
console.log(num2); // 4

let arr1 = [‘Amy’, ‘John’];
let arr2 = arr1;
// Changing elements’ value in arr2 leads to changing elements’ value in arr1
arr2[0] = ‘Jane’;
console.log(arr1); // [“Jane”, “John”]
console.log(arr2); // [“Jane”, “John”]

7. Callback

In JavaScript, a callback function is a function that is executed after another function is called. You can pass a callback function as a parameter to other functions.

So why do we use callback? Normally, the code we write runs sequentially from top to bottom. In some cases, however, there’re tasks need to be done before executing others. This is when callback comes in handy.

const fetchUsers = callback => {
  setTimeout(() => {
    let response = ‘[{name: “Amy”}, {name: “John”}]’;
  }, 500);
const showUsers = users => console.log(users);

In the example above, we call fetchUsers function and pass **showUsers **callback function as a parameter. When all the data is fully loaded, showUsers will display it on the screen.

8. Prototype

Whenever we create a function or object in JavaScript, a prototype property will be added inside them. A prototype is an object associated with functions and objects by default, in which we can attach additional properties that can be inherited by other objects.


function Person() { = ‘Amy’;
  this.age = 28;
Person.prototype.job = ‘Programmer’;
Person.prototype.showName = function() {
  console.log(‘My name is ‘ +;
let person = new Person();
person.showName(); // My name is Amy

9. Class

Prior to ES6, there are no classes in JavaScript. You can only approach the like-class concept in a functional way.

function Book(title) {
  this.title = title;

Book.prototype.showTitle = function() {
let book = new Book(‘JavaScript’);
book.showTitle(); // JavaScript

In ES6, you can create an actual class like any class-based language background:

class Book {
  constructor(title) {
    this.title = title;
  showBook() {
let book = new Book(‘ES6’);

It’s convenient because it unifies several way of creating classes into a single one.

10. Destructing

It’s a clean way to extract properties from objects.

Basic usage:

const person = {
  name: ‘Amy’,
  age: 28
let { name, age } = person;
console.log(name); // Amy
console.log(age); // 28

You can keep variables the same as properties name like above or define the new ones:

let { name: newName, age: newAge } = person;

console.log(newName); // Amy
console.log(newAge); // 28

11. Spread Operator

This one will give you access to the insides of an iterable object. Simply talk, it’s a quick and concise way for adding items to arrays, combining objects, or pull the individual items out of an array and then pass them to a function.

// Combining Arrays
let arr1 = [1, 2, 3];
let arr2 = [4, 5, 6];
let arr3 = […arr1, …arr2];
console.log(arr3); // [1, 2, 3, 4, 5, 6]
// Combining Objects
let obj1 = {
  name: ‘Amy’,
  age: 28
let obj2 = {
  job: ‘programmer’
let obj3 = { …obj1, …obj2 };
console.log(obj3); // {name: “Amy”, age: 28, job: “programmer”}
// Spreading out an array and pass it to a function
const sum = (…arr) => {
  const length = arr.length;
  let sum = 0;
  for (let i = 0; i < length; i++) {
    sum += arr[i];
  return sum;
let arr = [3, 5, 3, 2, 1];
console.log(sum(…arr)); // 14
console.log(sum(3, 5, 4, 1)); // 13


Do you fully understand all of the concepts above? If not, it’s time to examine all of them and be ready to take your skills to the next level.

Do I miss anything? Please leave the comment to let me know.

How to Use Hotwire Rails


We are back with another exciting and much-talked-about Rails tutorial on how to use Hotwire with the Rails application. This Hotwire Rails tutorial is an alternate method for building modern web applications that consume a pinch of JavaScript.

Rails 7 Hotwire is the default front-end framework shipped with Rails 7 after it was launched. It is used to represent HTML over the wire in the Rails application. Previously, we used to add a hotwire-rails gem in our gem file and then run rails hotwire: install. However, with the introduction of Rails 7, the gem got deprecated. Now, we use turbo-rails and stimulus rails directly, which work as Hotwire’s SPA-like page accelerator and Hotwire’s modest JavaScript framework.

What is Hotwire?

Hotwire is a package of different frameworks that help to build applications. It simplifies the developer’s work for writing web pages without the need to write JavaScript, and instead sending HTML code over the wire.

Introduction to The Hotwire Framework:

1. Turbo:

It uses simplified techniques to build web applications while decreasing the usage of JavaScript in the application. Turbo offers numerous handling methods for the HTML data sent over the wire and displaying the application’s data without actually loading the entire page. It helps to maintain the simplicity of web applications without destroying the single-page application experience by using the below techniques:

Turbo Frames: Turbo Frames help to load the different sections of our markup without any dependency as it divides the page into different contexts separately called frames and updates these frames individually.
Turbo Drive: Every link doesn’t have to make the entire page reload when clicked. Only the HTML contained within the tag will be displayed.
Turbo Streams: To add real-time features to the application, this technique is used. It helps to bring real-time data to the application using CRUD actions.

2. Stimulus

It represents the JavaScript framework, which is required when JS is a requirement in the application. The interaction with the HTML is possible with the help of a stimulus, as the controllers that help those interactions are written by a stimulus.

3. Strada

Not much information is available about Strada as it has not been officially released yet. However, it works with native applications, and by using HTML bridge attributes, interaction is made possible between web applications and native apps.

Simple diagrammatic representation of Hotwire Stack:

Prerequisites For Hotwire Rails Tutorial

As we are implementing the Ruby on Rails Hotwire tutorial, make sure about the following installations before you can get started.

  • Ruby on Rails
  • Hotwire gem
  • PostgreSQL/SQLite (choose any one database)
  • Turbo Rails
  • Stimulus.js

Looking for an enthusiastic team of ROR developers to shape the vision of your web project?
Contact Bacancy today and hire Ruby developers to start building your dream project!

Create a new Rails Project

Find the following commands to create a rails application.

mkdir ~/projects/railshotwire
cd ~/projects/railshotwire
echo "source ''" > Gemfile
echo "gem 'rails', '~> 7.0.0'" >> Gemfile
bundle install  
bundle exec rails new . --force -d=postgresql

Now create some files for the project, up till now no usage of Rails Hotwire can be seen.
Fire the following command in your terminal.

  • For creating a default controller for the application
echo "class HomeController < ApplicationController" > app/controllers/home_controller.rb
echo "end" >> app/controllers/home_controller.rb
  • For creating another controller for the application
echo "class OtherController < ApplicationController" > app/controllers/other_controller.rb
echo "end" >> app/controllers/home_controller.rb
  • For creating routes for the application
echo "Rails.application.routes.draw do" > config/routes.rb
echo '  get "home/index"' >> config/routes.rb
echo '  get "other/index"' >> config/routes.rb
echo '  root to: "home#index"' >> config/routes.rb
echo 'end' >> config/routes.rb
  • For creating a default view for the application
mkdir app/views/home
echo '<h1>This is Rails Hotwire homepage</h1>' > app/views/home/index.html.erb
echo '<div><%= link_to "Enter to other page", other_index_path %></div>' >> app/views/home/index.html.erb
  • For creating another view for the application
mkdir app/views/other
echo '<h1>This is Another page</h1>' > app/views/other/index.html.erb
echo '<div><%= link_to "Enter to home page", root_path %></div>' >> app/views/other/index.html.erb
  • For creating a database and schema.rb file for the application
bin/rails db:create
bin/rails db:migrate
  • For checking the application run bin/rails s and open your browser, your running application will have the below view.

Rails Hotwire Home Page

Additionally, you can clone the code and browse through the project. Here’s the source code of the repository: Rails 7 Hotwire application

Now, let’s see how Hotwire Rails can work its magic with various Turbo techniques.

Hotwire Rails: Turbo Drive

Go to your localhost:3000 on your web browser and right-click on the Inspect and open a Network tab of the DevTools of the browser.

Now click on go to another page link that appears on the home page to redirect from the home page to another page. In our Network tab, we can see that this action of navigation is achieved via XHR. It appears only the part inside HTML is reloaded, here neither the CSS is reloaded nor the JS is reloaded when the navigation action is performed.

Hotwire Rails Turbo Drive

By performing this action we can see that Turbo Drive helps to represent the HTML response without loading the full page and only follows redirect and reindeer HTML responses which helps to make the application faster to access.

Hotwire Rails: Turbo Frame

This technique helps to divide the current page into different sections called frames that can be updated separately independently when new data is added from the server.
Below we discuss the different use cases of Turbo frame like inline edition, sorting, searching, and filtering of data.

Let’s perform some practical actions to see the example of these use cases.

Make changes in the app/controllers/home_controller.rb file


class HomeController < ApplicationController
   def turbo_frame_form
   def turbo_frame submit
      extracted_anynumber = params[:any][:anynumber]
      render :turbo_frame_form, status: :ok, locals: {anynumber: extracted_anynumber,      comment: 'turbo_frame_submit ok' }

Turbo Frame

Add app/views/home/turbo_frame_form.html.erb file to the application and add this content inside the file.



    <%= turbo_frame_tag 'anyframe' do %>
          <h2>Frame view</h2>
          <%= form_with scope: :any, url: turbo_frame_submit_path, local: true do |form| %>
              <%= form.label :anynumber, 'Type an integer (odd or even)', 'class' => 'my-0  d-inline'  %>
              <%= form.text_field :anynumber, type: 'number', 'required' => 'true', 'value' => "#{local_assigns[:anynumber] || 0}",  'aria-describedby' => 'anynumber' %>
              <%= form.submit 'Submit this number', 'id' => 'submit-number' %>
          <% end %>
        <h2>Data of the view</h2>
        <pre style="font-size: .7rem;"><%= JSON.pretty_generate(local_assigns) %></pre> 
    <% end %>


Add the content inside file

Make some adjustments in routes.rb


Rails.application.routes.draw do
  get 'home/index'
  get 'other/index'

  get '/home/turbo_frame_form' => 'home#turbo_frame_form', as: 'turbo_frame_form'
  post '/home/turbo_frame_submit' => 'home#turbo_frame_submit', as: 'turbo_frame_submit'

  root to: "home#index"
  • Next step is to change homepage view in app/views/home/index.html.erb


<h1>This is Rails Hotwire home page</h1>
<div><%= link_to "Enter to other page", other_index_path %></div>

<%= turbo_frame_tag 'anyframe' do %>        
      <h2>Home view</h2>
      <%= form_with scope: :any, url: turbo_frame_submit_path, local: true do |form| %>
          <%= form.label :anynumber, 'Type an integer (odd or even)', 'class' => 'my-0  d-inline'  %>
          <%= form.text_field :anynumber, type: 'number', 'required' => 'true', 'value' => "#{local_assigns[:anynumber] || 0}",  'aria-describedby' => 'anynumber' %>
          <%= form.submit 'Submit this number', 'id' => 'submit-number' %>
      <% end %>
<% end %>

Change HomePage

After making all the changes, restart the rails server and refresh the browser, the default view will appear on the browser.

restart the rails serverNow in the field enter any digit, after entering the digit click on submit button, and as the submit button is clicked we can see the Turbo Frame in action in the below screen, we can observe that the frame part changed, the first title and first link didn’t move.

submit button is clicked

Hotwire Rails: Turbo Streams

Turbo Streams deliver page updates over WebSocket, SSE or in response to form submissions by only using HTML and a series of CRUD-like operations, you are free to say that either

  • Update the piece of HTML while responding to all the other actions like the post, put, patch, and delete except the GET action.
  • Transmit a change to all users, without reloading the browser page.

This transmit can be represented by a simple example.

  • Make changes in app/controllers/other_controller.rb file of rails application


class OtherController < ApplicationController

  def post_something
    respond_to do |format|
      format.turbo_stream {  }


file of rails application

Add the below line in routes.rb file of the application


post '/other/post_something' => 'other#post_something', as: 'post_something'
Add the below line

Superb! Rails will now attempt to locate the app/views/other/post_something.turbo_stream.erb template at any moment the ‘/other/post_something’ endpoint is reached.

For this, we need to add app/views/other/post_something.turbo_stream.erb template in the rails application.


<turbo-stream action="append" target="messages">
    <div id="message_1">This changes the existing message!</div>
Add template in the rails application

This states that the response will try to append the template of the turbo frame with ID “messages”.

Now change the index.html.erb file in app/views/other paths with the below content.


<h1>This is Another page</h1>
<div><%= link_to "Enter to home page", root_path %></div>

<div style="margin-top: 3rem;">
  <%= form_with scope: :any, url: post_something_path do |form| %>
      <%= form.submit 'Post any message %>
  <% end %>
  <turbo-frame id="messages">
    <div>An empty message</div>
change the index.html.erb file
  • After making all the changes, restart the rails server and refresh the browser, and go to the other page.

go to the other page

  • Once the above screen appears, click on the Post any message button

Post any message button

This action shows that after submitting the response, the Turbo Streams help the developer to append the message, without reloading the page.

Another use case we can test is that rather than appending the message, the developer replaces the message. For that, we need to change the content of app/views/other/post_something.turbo_stream.erb template file and change the value of the action attribute from append to replace and check the changes in the browser.


<turbo-stream action="replace" target="messages">
    <div id="message_1">This changes the existing message!</div>

change the value of the action attributeWhen we click on Post any message button, the message that appear below that button will get replaced with the message that is mentioned in the app/views/other/post_something.turbo_stream.erb template

click on Post any message button


There are some cases in an application where JS is needed, therefore to cover those scenarios we require Hotwire JS tool. Hotwire has a JS tool because in some scenarios Turbo-* tools are not sufficient. But as we know that Hotwire is used to reduce the usage of JS in an application, Stimulus considers HTML as the single source of truth. Consider the case where we have to give elements on a page some JavaScript attributes, such as data controller, data-action, and data target. For that, a stimulus controller that can access elements and receive events based on those characteristics will be created.

Make a change in app/views/other/index.html.erb template file in rails application


<h1>This is Another page</h1>
<div><%= link_to "Enter to home page", root_path %></div>

<div style="margin-top: 2rem;">
  <%= form_with scope: :any, url: post_something_path do |form| %>
      <%= form.submit 'Post something' %>
  <% end %>
  <turbo-frame id="messages">
    <div>An empty message</div>

<div style="margin-top: 2rem;">
  <div data-controller="hello">
    <input data-hello-target="name" type="text">
    <button data-action="click->hello#greet">
    <span data-hello-target="output">

Make A changeMake changes in the hello_controller.js in path app/JavaScript/controllers and add a stimulus controller in the file, which helps to bring the HTML into life.


import { Controller } from "@hotwired/stimulus"

export default class extends Controller {
  static targets = [ "name", "output" ]

  greet() {
    this.outputTarget.textContent =
      `Hello, ${this.nameTarget.value}!`

add a stimulus controller in the fileGo to your browser after making the changes in the code and click on Enter to other page link which will navigate to the localhost:3000/other/index page there you can see the changes implemented by the stimulus controller that is designed to augment your HTML with just enough behavior to make it more responsive.

With just a little bit of work, Turbo and Stimulus together offer a complete answer for applications that are quick and compelling.

Using Rails 7 Hotwire helps to load the pages at a faster speed and allows you to render templates on the server, where you have access to your whole domain model. It is a productive development experience in ROR, without compromising any of the speed or responsiveness associated with SPA.

The essential JavaScript concepts that you should understand

As a JavaScript developer of any level, you need to understand its foundational concepts and some of the new ideas that help us developing code. In this article, we are going to review 16 basic concepts. So without further ado, let’s get to it.

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

Coding 101: Who is Json?

While Voorhees, Statham, and Derulo all have their talents, both good and evil, I would propose that the best Json goes to the machine-readable file format. Json, or rather JSON, is an important acronym in the tech world. JSON stands for JavaScript Object Notation. It is frequently used by data professionals, software engineers, and folks in IT. If you have never written a piece of code, this will seem like a foreign language to you. Guess what? It is.

Let’s break it down.

{ JS: JavaScript }

JavaScript is a scripting or programming _language _that allows you to implement complex features on web pages (per Mozilla). This is one of the most popular programming languages used for constructing websites. Whether you are visiting or , or almost any website, it is highly likely that the construction relies, to some extent, on JavaScript. How do I know that they use JavaScript?

Let’s take a look.

  1. Open up a new tab and go to (see images below).
  2. Right click anywhere on the page and select, “Inspect Element” or “Inspect”, depending on your browser. This will open a new panel in the window from the bottom half.
  3. In this new panel, confirm that you are on the “Elements” or “Inspector” tab. Scroll up or down until you see the word, “text/javascript” or a file name that ends in “.js”.
