JavaScript is a multi-paradigm language. It supports event-driven, functional, and imperative, including object-oriented and prototype-based, programming styles. JavaScript was initially used only for client side. These days JavaScript is used as a server-side programming language as well. To summarize in just one simple sentence — JavaScript is the language of the web. The JavaScript world is a rich environment with dozens of tools, libraries, and frameworks. But, with lots of options comes a lot of confusion. It really is a double-edged sword. While you get lots of space for creativity and experimentation, sometimes you are unsure about what library or framework to choose. The front-end framework you choose can make or break your project in the long run. In this article, we will look at some of the most popular JavaScript frameworks, and how they fare against each other. We’ll examine five different perspectives of these frameworks, which eases the process of deciding on your next JavaScript framework. Whether you are choosing from one of these popular JavaScript frameworks, or something more esoteric, you should take each of these aspects into consideration. So, without ado, we will go ahead and take a look at the most popular JavaScript frameworks for 2020! Vue.js is an open-source JavaScript environment designed to simplify and streamline user interface design. The framework, also the ideal blend of Angular and React, has proven itself to be the perfect choice for developing a lightweight, two-way data binding application to the angle structure and server rendering of the React JS framework. Vue.js was nominated as the most popular JavaScript interface on GitHub with 118 thousand stars last year. Vue.js may seem like an ideal JavaScript structure for software development, but it also has its pros and cons. You can also read more about the framework Vue.js in our article here Supported by Facebook, Instagram and other well-known organizations, React is one of the best JavaScript frameworks for the past five years. Also, React.js or React JS, more than 38% of developers worldwide use the front end infrastructure. Netflix, Flipboard, PayPal and the BBC are the first organizations to use React. Let's take a look at all the pros and cons of React. Angular.js is a full-featured front-end JavaScript environment supported by Google and other famous corporations. This structure is known for its potential capabilities like fast code generation, two-way data binding, and testing parts of an application. Although hundreds of companies and developers enjoy using the Angular front end Javascript framework, there are pros and cons of this technology. Ember.js has been used in the design of many complex websites, like Kickstarter, Heroku, and LinkedIn. Ember.js is ideal for developing complex web applications, and the string system of templates with which it is delivered contributes to a significant reduction in load time. The front end JavaScript Framework also focuses on scalability so that developers can quickly work with both mobile and web applications. Backbone is an MV* framework. Backbone partly implements an MVC architecture, as Backbone’s View part carries out the responsibilities of the Controller. Backbone has a strong dependency on the jQuery and the Underscore library that gives us many helper functions for convenient cross-browser work with JavaScript. Unlike many other full-fledged JavaScript frameworks, Backbone attempts to reduce complexity to avoid performance issues. More specifically, you won't get performance problems because of two-way data binding or built-in loops like in AngularJS. Our team's favorite is Vue.js, one of those selected here. But the real answer depends entirely on the project. Do you need the most popular JavaScript framework? Probably no. How about the biggest and the biggest or the smallest and the lightest? These factors may or may not matter. Each developer has his own opinion, but we all need to understand one thing that cannot find the best structure among the JavaScript frameworks. Choosing the most appropriate structure depends entirely on the needs of a project. Thus, it is to consider the pros and cons of all the above frameworks and decide which one to start a project with.
