Window.console in JavaScript

In JavaScript, window.console or console object is under-rated with only console.log() being used most of the time. However, the console object comes with a lot of advanced features. In this article, we will be discussing the functions available on the console that can be handy at times.

In JavaScript, window.console or console object is under-rated with only console.log() being used most of the time. However, the console object comes with a lot of advanced features.

In this article, we will be discussing the functions available on the console that can be handy at times.

A deeper look into the console

Besides console.log(), there are a lot of other methods also available. You can try looking for the suggestions list in the browser’s console.


console.log() is the most commonly used function in JavaScript to log values. It just logs/prints the value that is passed to the function.

We can also concatenate multiple values using console.log(). Simply call console.log() with multiple parameters and all the values will be concatenated.

You can even pass multiple objects and the browser’s console will show them side by side.

Following are some of the examples of concatenation with console.log:


While console.log() can be used to print an object, we can also use console.table() to pretty print an object in the form of a table.

Just pass the object to print the object in a more readable format.

Notice, how it prints the values for the nested object.


It is used to print warning messages in the browser’s console.


It is used to print error messages in the console.


This can be used to calculate the time elapsed by our code to execute.

Before starting the execution of any operation, start the timer with console.time(‘TIMER_NAME’) and after the execution of the code, end the timer with console.timeEnd(‘TIMER_NAME’).

As soon as you call the timeEnd function, the elapsed time will get printed in the console.

The timer name should be same for time() and timeEnd()


This command is used to clear the console.

Running the last command resulted in the console being cleared with the following message.

Which is JavaScript Frameworks for Front-End Development in 2020

Which is JavaScript Frameworks for Front-End Development in 2020

React vs Vue vs Angular vs Ember vs Backbone.js: Which is best JavaScript framework For Front-End Development in 2020?

Front-end developers might know this game already: you type “top JavaScript frameworks” into Google and you get so many JavaScript frameworks from which to choose.

There are always more choices for JavaScript frameworks. And it's always tough to choose a JavaScript framework for front-end development.

So, what are front-end developers looking for in their tech stacks? As a full-time developer, I know it comes down to rapid development and easy-to-make UIs.

Rather than try to be decisive, we, 450+ developers at ValueCoders software development company voted and shortlisted a few of the best JavaScript frameworks.

And, Our Vote Goes to React

I was not surprised to see this.Most of our developers voted for React as one of the best JavaScript frameworks. There have been plenty of projects along the way that our front-end developers are handling that highlighted the strengths of the JS framework. React provides a combination of the following:

  • Reusable components
  • Synchronization of state and view
  • Routing and template system

Our developers implement front-end logic by relying heavily on React. At the same time, I was surprised by how simple it was to create applications with React.

Overview of App

The application is simple. It’s a studio management app for music teachers that helps them focus more on their teaching and less on the management of their music studio.

The key challenge was creating one ‘Activity Dashboard’ for teachers where they could manage all their students' activities and track their progress over time. We overcame this challenge by using Redux libraries to build the platform. We built a teacher’s studio from where they could manage their students' progress, showcase new music lessons, chat with them, compare students music playing with live music, and provide them feedback.

So, this is my experience with React JS. But many would argue that Vue is one of the best front-end JavaScript frameworks with many useful tools.

Front-end developers are the ones deciding which JavaScript framework will do the job. In doing so, they face a lot of challenges because they need to decide what they’ve always needed. Often, we have to choose JavaScript frameworks now, not after a week of research. In that case, most developers go with what they know. But maybe the stacks you’re familiar with are no longer cutting it in terms of performance.

Even just choosing among Angular, React, & Vue, it is difficult for new developers. Rather than making it more exhaustive for you, here is the list of top JavaScript frameworks for front-end developers.

The Big 5

The five JavaScript frameworks that currently dominate the market in terms of popularity and usage are:

  • React
  • Vue
  • Angular
  • Ember
  • Backbone.js.

They each have large communities. If you are a front-end developer or are going to start your new project on front-end technologies, these five are your best bets. Here’s a look at the npm trends over the last six months.

1. React

React is a definite leader in the JS world. This JavaScript framework uses a reactive approach and also introduces many of its own concepts for frontend web development.

To use React , you’ll have to learn to use a plethora of additional tools to reach high flexibility in front-end development. For example, here's a less exhaustive list of libraries you can use with React: Redux, MobX, Fluxy, Fluxible, or RefluxJS. React can also be used with jQuery AJAX, fetch API, Superagent, and Axios.

Concurrent Mode

React is constantly working towards improving concurrent mode. To take this forward, React Conf 2019 wrapped up last month where the React team talked about improving Concurrent Mode and the Suspense model. Both the features make React apps more responsive by rendering trees without blocking threads. This allows React to focus on high priority tasks like responding to user input.


React also introduced Suspense to improve the developer’s experience when handling asynchronous data fetching on React apps. In short, the new update to Suspense lets the component wait until the condition is met.

The React team is also working on Hooks which was one of the most awaited features of React. As per the latest updates, React hooks will be designed in a way that it supports all the important features: server-side rendering, accessibility, concurrent mode, and suspense.

React applications are divided into multiple components that contain both business logic and HTML markup functions. To improve the communication between components, developers can use either Flux or a similar JavaScript library.

React also introduced objects, like state and props. With the state and props objects, you can simply pass data from a component to the layout or from a parent component to a child component.

Introduction to the React ecosystem:

  • The React library plus React router for implementing routes.
  • React-DOM for DOM manipulation.
  • React developer tools for Firefox and Chrome browsers.
  • React JSX, a markup language that mixes HTML into JavaScript.
  • React Create App command line interface to set up a React project.
  • Redux and Axios libraries to organize communication with the backend team.

No doubt, React is one of the most popular JavaScript frameworks. And, I think that React can be your first choice for creating advanced-grade apps.

2. Angular 2 to Angular 9

Angular 9 will mark a turning point revealed by the Angular team at the recent AngularConnect 2019. According to the update, the team is planning to make the Angular Ivy compiler available for all apps. The main benefit of Angular Ivy is that it is able to reduce the size of applications.

Angular today has become very advanced and modular to use for front-end development. Previously you could insert a link to the AngularJS library in the main HTML file, but now you can do the same by installing separate modules.

Angular's flexibility is commendable. That’s why Angular's 1.x versions are still in demand. However, many current developers rely on Angular 2+ because of its MVC architecture that has substantially changed to a component based architecture.

Angular has a couple of additional challenges. You're almost obliged to use TypeScript to ensure type safety in Angular apps. TypeScript makes the Angular 2+ framework not so pleasant to work with.

Angular’s ecosystem is comprised of:

  • For quick project setup, Angular's command line interface is helpful.
  • Developers will get a set of modules for Angular projects: @angular/common, @angular/compiler, @angular/core, @angular/forms, @angular/http, @angular/platform-browser, @angular/platform-browser-dynamic, @angular/router, and @angular/upgrade.
  • Angular uses Zone.js a JavaScript library to implement zones in Angular apps.
  • TypeScript and CoffeeScript both can be used with Angular.
  • For communication with server-side apps, Angular uses RxJS and the Observable pattern.
  • Angular Augury for debugging Angular apps.
  • Angular Universal for creating server-side apps with Angular.

Angular2 is a complete JavaScript framework with all the tools a modern front-end developer needs. You can choose Angular if you don’t like to work with additional libraries as with React.

3. Vue

The Snyk JavaScript framework report for 2019 is out. The report mainly focused on security risks in both React and Angular.

The concept of Vue has been taken from Angular and React, but Vue is better in many ways. I’ll talk about its features, but first check out what the Synk report says about Vue's front-end security. Vue has been downloaded 40 million times this year and records only four direct vulnerabilities. All of them have been fixed.

For any front-end developer unfamiliar with Vue, let’s clarify several points.

With Vue you store component logic and layouts along with stylesheets in one file. This the same way React works, without stylesheets. To let components talk to each other, Vue uses the props and state objects. This approach also existed in React before Vue adopted it.

Similar to Angular, Vue wants you to mix HTML layouts with JavaScript. You have to use Vue directives such as v-bind or v-if to interpolate values from the component logic to templates.

One of the reasons why Vue is worth considering instead of React is because of the Redux library that’s often used in large-scale React applications. As explained in the React section, when a React+Redux app grows bigger, you’ll spend a lot of time applying small changes to multiple files instead of actually working on features. The Vuex library – a Flux-like state management tool designed for Vue – seems less unwieldy than Redux.

If you're choosing between Vue and Angular, the reasons to opt for Vue over Angular can be reduced to the following: Angular is an over-complicated, full-fledged framework with a restrictive nature; Vue is much simpler and less restrictive than Angular.

Another advantage of Vue over Angular and React is that you don’t have to learn JavaScript once more.

An introduction to the VueJS ecosystem:

  • Vuex comes with a dedicated library for application management.
  • Vuex is similar to the concept of Flux.
  • You will get Vue-loader for components and vue.js devtools for Chrome and Firefox browsers.
  • Vue-resource and Axios tools for communication between Vue and the backend source.
  • Vue.js support Nuxt.js for creating server-side applications with Vue; Nuxt.js is basically a competitor to Angular Universal.
  • You will get a Weex JavaScript library with Vue syntax that is used for mobile app development.

Vue is excellent in terms of its workflow to other frameworks. I might opt for Vue because it’s less complicated than React and Angular JS and a great choice for developing enterprise-level apps.

4. Ember

Ember 3.13 released this year with some new updates and features. Ember is just like Backbone and AngularJS, and is also one of the oldest JavaScript frameworks. But with the new update, Ember 3.13 is compatible with new bug fixes, performance improvements, and deprecation. Tracked property updates have also been introduced that allow simpler ways of tracking state change in the ergonomic system of Ember apps.

Ember has a relatively intricate architecture, which will allow you to quickly build huge client-side applications. It realizes a typical MVC JavaScript framework, and Ember’s architecture comprises the following parts: adapters, components, controllers, helpers, models, routes, services, templates, utils, and addons.

One of Ember’s best features is its command line interface tool. The Ember CLI helps front-end developers be highly productive and lets them complete projects on time. You can not only create new projects with ready setups, but you can also create controllers, components, and project files using automatic generation.

The EmberJS ecosystem is comprised of:

  • Ember CLI tool for quick prototyping and managing dependencies.
  • Ember server built into the framework for the development of apps.
  • You'll get Ember.js library and Ember Data for data management.
  • Handlebars template engine for Ember applications.
  • QUnit testing framework for Ember.
  • Ember Inspector development tool for Chrome and Firefox browsers.
  • Ember Observer for public storage and Ember addons to implement generic functionalities.

Although Ember is underrated, it's perfect for creating complex client-side apps.

5. Backbone.js

Backbone is a JavaScript framework based on the MVC architecture. Backbone’s View part carries out the responsibilities of the Controller. The View helps implement component logic similarly to a Controller in MVC. Backbone view can use engines like Mustache and Underscore.js.

Backbone is an easy to use JavaScript framework that allows for quick development of single page applications. To use Backbone.js to the fullest extent, you’ll have to choose tools: Chaplin, Marionette, Thorax, Handlebars or Mustache, and so on.

If you need to design an app that has different type of users, Backbone collections (arrays) can be used here to separate the models. Backbone.Events, can be used with Backbone models, collections, routes, and views.

Introducing the BackboneJS ecosystem:

  • The Backbone library consists of events, models, collections, views, and router.
  • Underscore.js, a JavaScript library with helper functions that you can use to write cross-browser JavaScript.
  • You can use template engines such as Mustache and jQuery-tmpl.
  • BackPlug online repository with a lot of ready solutions for Backbone-based apps.
  • Backbone generator CLI for building Backbone apps.
  • Marionette, Thorax, and Chaplin JavaScript libraries to develop an advanced architecture for Backbone apps.

Backbone.js is a perfect choice for frontend and backend development as it supports REST APIs that are used to synchronize the frontend and backend.
