Are you wondering what JavaScript framework or library you should use to land a job in 2019? In this post, I am going to go over a comparison of the most popular JavaScript frameworks that are available today. By the end of this post, you will be ready to pick the right framework to help you land a front-end developer job in 2019.

If you would rather watch a video to learn about this, checkout this video by Mosh, comparing React, Angular and Vue. It will help you decide which framework to choose to land a job in 2019.


It’s 2019, and the StackOverflow Developer survey results for this year are out. Guess what? For the seventh year in a row, JavaScript has been voted as the most popular programming language.


With JavaScript being the most used programming language in the world, JavaScript Web frameworks and libraries like React, Angular and Vue are thriving. In this post, we are going to look at the most popular web framework in 2019.

And the Winner is…

React is the most loved and most wanted web framework by developers in 2019.


React tops the list and has been voted as the most “wanted “and most “loved” web framework. It is closely followed by Vue this year. Angular seems to be losing its popularity compared to the previous years.


React is the most loved and most wanted web framework by developers in 2019.## Three Most Popular Web Frameworks Today

Angular is a full blown web framework. Ithas been around the longest among the three.Angular was developed by Google and first released in 2010. It is a TypeScript based JavaScript framework. Angular (version 2 and above), originally released in September 2016, is a complete rewrite of AngularJS (released in October 2010).

React is a JavaScript library that is used to build frontend applications. React is backed by Facebook and was open sourced by Facebook in 2013. Ever since then, it has consistently gained popularity and today ranks as the most popular web library in the world. React is used far more at Facebook than Angular is at Google if it’s any indication as to how big Facebook is betting on this technology. They also have a dedicated team of developers working on React.

**Vue **is the new kid on the block. Unlike React and Angular, Vue is not backed by any corporation like Facebook or Google. Vue was developed by a group of passionate developers. It has elements of both React and Angular, and in my opinion contains the best of both worlds.

Why is React the most popular?

I did a quick search on Google trends to compare the search terms “React”, “Angular” and “Vue”. And it has the same results as the StackOverflow survey.

So why does everyone like React so much? Let’s study some differences and commonalities between the three most wanted web frameworks/libraries and see why React is everyone’s favorite.

Corporate Backing

**Angular **is developed and maintained by **Google. **Google uses Angular in several internal products as well as the Google Adwords application. This is one of the reasons, why Angular is trusted in the developer community.

React is backed by Facebook and was open sourced by Facebook in 2013. Facebook has a dedicated team of engineers who are working on React and making React better everyday. Since Facebook is heavily invested in React, many internal Facebook products are coded in React. With Facebook’s heavy involvement in React, the library has gained a lot of trust over the years.

Vue is not backed by any big corporation like React. Although Vue is not backed by big names, it has gained a huge name in the open source community. It is fairly new compared to React and is backed by a group of open source contributors.

React is the most loved and most wanted web framework by developers in 2019.## Job Prospects

Alright, let’s talk about Jobs. Ultimately, you want to invest time and learn something that gets you a job in the market.

We know Vue is the most recent addition to the family of web frameworks and it seems to be liked by many. But as of today, there are tons of React and Angular jobs when compared to Vue jobs in the market. This is also because, both Angular and React have been around longer. Lots of companies have adopted these technologies, hence creating many jobs in the market. But I am sure if you give Vue a few more years, it will start to catch up.

React is the most loved and most wanted web framework by developers in 2019.
I did a quick search on LinkedIn to compare job postings within the United States on React, Angular and Vue. This is what I found, React topped the list with about 59000 postings, followed by Angular with 33103 postings. Vue had the least among the three with only 6442 postings, indicating that it is yet to be adopted by companies in a large scale.

Let’s take a look at a similar search on _Indeed.com _for job postings within the U.S. Based on the numbers here, there is a huge demand for React developers, with 13000 job postings, closely followed by Angular.

React is the most loved and most wanted web framework by developers in 2019.## Learning Curve


Angular has many topics to learn, starting from basic ones such as directives, modules, decorators, components, services, dependency injection, pipes, and templates. After that, there are more advanced topics such as change detection, zones, AoT compilation, and Rx.js.

The entry barrier for Angular is clearly higher than for React. The sheer number of new concepts is confusing to newcomers. And even after you’ve started, the experience might be a bit rough since you need to keep in mind things like Rx.js subscription management and change detection performance.


React uses JavaScript XML (JSX) which is a way of writing HTML within JavaScript code. JSX makes sense since React believes in functional programming.

For a typical web developer, initially JSX could be bit of a learning curve. Although, JSX is a different approach, it is very similar to HTML and a developer should be able to grasp it with some practice.

You’ll also need to learn how to write components, manage internal state, and use props for configuration. You don’t need to learn any new logical structures or loops since all of this is plain JavaScript. Once you’ve learned the basics, a routing library, and state management library, you’re ready to start building apps! This is far easier than learning Angular for a newbie.


Vue’s coding style is similar to what web developers are used to before the advent of React. Vue separates HTML, JavaScript and CSS like the traditional way of coding web applications.

It does allow JSX, if that is your preferred code style. Vue also has component lifecycle, but they are simple and much more intuitive than React. Vue also is a younger framework, so it made sure it took the best of React and addressed some of the problems with React.

React is the most loved and most wanted web framework by developers in 2019.## Mobile Solutions



Ionic is a framework for developing hybrid mobile applications. It uses a Cordova container that is incorporated with Angular. Ionic provides a robust UI component library that is easy to set up and develop hybrid mobile applications with. However, the resulting app on a device is simply a web app inside of a native webview container. Because of this, the apps can be slow and laggy. Recently, Ionic has announced compatibility with React giving Ionic developers the freedom to choose between Angular and React.

NativeScript + Angular

NativeScript lets you build native mobile apps on both iOS and Android. It can be used with a variety of frameworks. If you know Angular, then you can use NativeScript with Angular to build native mobile apps.

The NativeScript core team works with the Angular team at Google to ensure NativeScript and Angular are integrated. With this you can create native mobile apps with good performance. The only drawback here is that NativeScript has to constantly be in sync with the latest developments in the Angular world. Since NativeScript and Angular are two different solutions coming from two different companies, we never know when NativeScript may stop support for building apps with Angular.


React Native

The mobile solution that was born out of React is React Native. It is used to build native mobile apps using JavaScript and React. Today many fortune 500 companies are using it for their mobile space.

It is backed by Facebook, and was open sourced a few years ago. It is essentially React code. A React developer can easily pick up React Native, since the code is all written in JavaScript and React. The only difference is that instead of web components, it comes with native mobile components for iOS and Android.

React Native is by far the most used and popular cross-platform mobile framework. Learning this will give you plenty of job opportunities.



Vue has Vue-Native. The interesting thing about it is that, it is essentially a wrapper around React Native. Under the hoods, you need to setup React Native. This is not a stand-alone solution and cannot be used without React Native.

NativeScript + Vue

Just like NativeScript can be used with Angular, it can also be used with Vue. It enables you to build native mobile apps using NativeScript and Vue. Again, the drawback here is that NativeScript needs to constantly be updated to the latest development in Vue. And since they are coming from different teams and companies, we never know how long this support may last.

React is the most loved and most wanted web framework by developers in 2019.## Community and Developer Involvement

Let’s take a look at the open source community involvement in all the three frameworks to get a better idea on popularity, frequency of releases, etc. Take a look at this table below that compares them based on GitHub stats.

Something interesting to note here is that Vue, has the most number of stars among the three on GitHub. But it also has the least number of contributors. This means, people are interested in Vue, but it has still not gained the momentum that React and Angular has gained in the Open source community. React has around 126k stars, which is a lot for an open source library. This shows people like React as well. In comparison to that, Angular has only about 40k stars.

React also has a significant number of contributors. There are over 1290 contributors who are contributing to React, which is much more than Vue and Angular.

The final statistic on weekly downloads is quite intriguing. React has the most number of weekly downloads with a whopping number of 5,211,991. What is interesting is, Vue which is although new, comes second with 986,335 weekly downloads. You can notice here that Angular downloads are far less in comparison.

React is the most loved and most wanted web framework by developers in 2019.## Verdict

JavaScript frameworks and libraries are evolving everyday. There is a lot to look forward to in the coming years. With respect to 2019, **React **is still at the top. And learning React will help you find your dream front-end job. **Vue **is upcoming, but it is young. Finding a job with Vue skills may take a while. Angular is still out there, and used by many companies and enterprises. But it is losing its spark. Developers are not eager to learn Angular, as much as much as they would like to learn React or Vue.

Learning JavaScript: Working with Strings

Strings are the second most common data type used in JavaScript, and in many cases, since JavaScript is so widely used for web applications, it is the prominent data type. In this article I’ll discuss how strings work in JavaScript and how to work with them efficiently and effectively. I’ll also discuss some newer abilities of strings that are just being discovered and used.

Strings Defined

A string is any set of 0 or more characters enclosed in either single quotes or double quotes. The characters in a string can be alphabetic characters, numbers, symbols, and spaces. Here are some examples of JavaScript string literals:

"hello world"
'good bye, world!'
"1600 Pennsylvania Avenue"
'$*&!@ it!'

If you are using single quotes in your string, and you need to embed a single quote to write out a contraction, you use the backslash character (\) as an escape character. To see why you need to do this, let’s look at what happens when you don’t escape a single quote by writing out such a string in the JavaScript shell:

js> 'can't'
typein:1:5 SyntaxError: unexpected token: identifier:
typein:1:5 'can't'
typein:1:5 .....^

The interpreter can’t figure out what to do with the ‘t’ after the single quote.

Now watch what happens when we escape the single quote:

js> 'can\'t'

The escape character tells the interpreter to treat the single quote as an apostrophe and not as an “end-of-string” character.

You can embed other characters into a string, including the newline character (\n) and the tab character (\t). Here are some examples using the shell:

js> print("Hello, \n world!");
js> print("Hello, \tworld");
Hello,  world

Learning JavaScript: Computing with Object Methods

JavaScript has a set of built-in methods you can use with your user-defined objects. In this article I’m going to discuss several of these methods and how you can use them in your JavaScript programs.


The Object.assign method is used to make a copy of one object into another object. The syntax template for this method is:

Object.assign(target, source);

where source is the object you are copying from and target is the object you are copying into. This method returns the target object if you want to assign it.

Here is a sample program that demonstrates how to use Object.assign:

function Student(name, id, grades) {
  this.name = name;
  this.id = id;
  this.grades = grades;
let st1 = new Student("",0,[]);
et st2 = new Student("Jane Doe", 123, [91, 92, 93]);
Object.assign(st1, st2);
print(`${st1.name}, ${st1.id}\n[${st1.grades}]`);

The output from this program is:

Jane Doe, 123
[91, 92, 93]

A good reason to use this method is to make sure that a new object has all the properties and values of the old object. You may accidentally leave something out when writing your own method, while Object.assign will systematically make sure all properties and values are assigned to the new object.


The Object.create method creates a new object from an existing object prototype. Here is the syntax template for this method:

const|let|var object-name = Object.create(existing-object);

Let’s look at a few examples to see how this method works in practice. The first example creates a new object from a function and then creates a second object using Object.create:

function Student(name, id, grades) {
  this.name = name;
  this.id = id;
  this.grades = grades;
let st1 = new Student("Bob Green", 1234, [81, 77, 92]);
print(`${st1.name}, ${st1.id}\n${st1.grades}`);
let st2 = Object.create(st1);
print(`${st2.name}, ${st2.id}\n${st2.grades}`);

The output from this program is:

Bob Green, 1234
Bob Green, 1234

Code must be written to change the properties of the newly created object.

Learning JavaScript: Statements, Arithmetic, and Math

In this article I will discuss how to perform arithmetic and more advanced mathematical operations in JavaScript. First, though, I need to discuss how statements are formed and used in JavaScript.


JavaScript programs are made up of statements. A statement can be anything from a single function call or command to even just a variable name. JavaScript evaluates statements and then executes them.

For example, when you create a variable, you write a statement:

let number = 100;

JavaScript recognizes this as a statement and evaluates it by following its grammar rules. In this case the rule is to assign the expression on the right-hand sign of the assignment operator to the variable on the left-hand side.

As I mentioned above, a statement can be just an expression, as in the following example:

js> 1;

You can do the same thing with a variable:

js> let name = "Brendan";
js> name

Statements can be much more complicated than these examples, though, as you’ll learn as you get deeper into JavaScript. So far, you have seen examples of two types of statements — variable declaration and assignment statements and print statements.

JavaScript Arithmetic

Arithmetic is performed in JavaScript using the arithmetic operators. There are five arithmetic operators:

  • + (Addition)
  • - (Subtraction)
  • * (Multiplication)
  • / (Division)
  • % (Modulo/Remainder)

These operators are binary operators, meaning there must be values on either side of the operator. The + operator and the -operator can also be used as unary operators, in which can they are used to distinguish the sign (positive or negative) of a number.

The JavaScript arithmetic operators also have an order of operations, or precedence, they follow when used in a statement. The order of operations is: 1) modulo; 2) multiplication and division; 3) addition and subtraction.

You can use parentheses to modify the order of operations. When an arithmetic expression is placed inside parentheses, that expression is evaluated before any other operations.

For example, take the expression:

let n = 100 + 3 * 22;

Does n get the value 2266, 103 * 26, or does the variable get the value 166? Without parentheses the value of n is 166 because the multiplication takes place before the addition due to the precedence of the multiplication operator over the addition operator.
