I hope it can help you solve your doubts. Let Xiaobian lead you to study and learn "what are the open source JavaScript frameworks and libraries" this article.

JavaScript

The language has been endorsed by many tech leaders, one of whom is WordPress founder Matt Mullenweg, who hinted that WordPress developers should learn from it and clearly send a message to the WordPress community about its future importance. Mention of this is welcome. The transition to better technology will enable WordPress to keep up with future challenges.

JavaScript's open source stance is also one of the best. Contrary to popular belief, JavaScript is not a project, but a specification with open standards in which the language is evolved and maintained by its core team. ECMAScript, another fancy name for JavaScript, is not open source, but it also has an open standard.

When you check out GitHub, it's easy to see evidence of JavaScript's popularity. JavaScript is the most advanced programming language. Number of repositories. Its significant impact is also evident on Livecoding.tv, where members are struggling to create more videos in JavaScript than any other theme. At the time of writing, self-proclaimed host of educational entertainment sites. 45919 JavaScript videos.

Top open source JavaScript frameworks and libraries

Returning to the topic, JavaScript is fortunate to have a large community thriving on improving technology. There are hundreds of JavaScript frameworks and libraries available to developers, and the good news is that the best frameworks and libraries are open source. For JavaScript developers, it is now imperative to develop quickly using the best frameworks or libraries. The current market needs rapid development. Also, reinventing the wheel is not a good idea in the current market. Whether you're new to JavaScript or an experienced JavaScript developer, using libraries and frameworks can significantly improve your work.

1. Angular.js

Angular.js is one of the most popular JavaScript frameworks. Developers use it to build countless complex Web applications. Angular.js is designed with a single-page application pattern at its core, but it also supports the MVC architecture. Angular.js enables developers to extend HTML vocabulary at will by using JavaScript code on the front end.

Angular.js has not stopped growing since its birth in 2009. Angular 1 is currently stable at 1.5.8/1.2.30. You can also try Angular 2, which is a significant improvement over version 1, but it is still not popular with the global developer community.

Angular.js takes advantage of the important concept of data binding. Users interact with the interface, and when that interaction is complete, the view is then updated with new values, ensuring that everything is synchronized. DOM updates begin after the underlying logic has been executed in the model.

2. Backbone.js

Many of your friends probably don't plan to develop complex Web applications. In this case, relatively simple Web application frameworks such as Backbone.js can be used well for learning relevant knowledge. Backbone.js is an intuitive framework that speeds up the construction of simple Web applications and makes the process fun. Like Angular.js, Backbone.js also has MVC support. Other core features of Backbone.js include routing, RESTful API support, attribute state management, and more. You can also build single-page apps with Backbone.js.

Backbone.js is currently stable at version 1.3.3 and is available directly from GitHub.

3. D3.js

D3.js is an excellent JavaScript library that helps developers create rich web pages with data manipulation capabilities. D3.js combines SVG, HTML, and CSS. With D3.js, you can easily bind data to DOM and launch data-driven events. With the help of D3.js, we can also create high-quality data-driven web pages that provide better visual understanding of data content.

4. React.js

React.js is a very interesting JavaScript framework. Unlike other JavaScript frameworks, React.js is ideal for building highly scalable front-end user interfaces. React.js was born in 2013 under the BSD license and has grown rapidly due to its strengths in developing complex, beautiful user interfaces.

The core idea behind React.js is the virtual DOM. Virtual DOM acts as an intermediary between client and server to improve performance. Matching changes that occur in the virtual DOM with the server DOM ensures that only essential elements are updated, which makes the overall process much faster than traditional UI updates.

You can also leverage React for Material Design, which means you can build modern Web apps with very high performance levels.

5. jQuery

jQuery is a popular JavaScript library that includes event handling, animation, and much more. When building Web projects, you certainly don't want to waste time writing code for simple tasks. jQuery helps us solve this problem with its easy-to-use API. It also works with all major browsers. With jQuery, you can seamlessly control DOM and develop Ajax applications. With jQuery, developers don't have to worry about the underlying interactions and can easily develop Web applications of their own design.

jQuery also facilitates the separation of HTML and JavaScript code, enabling developers to write clean code with cross-browser compatibility. Web applications developed with jQuery are also easy to improve and extend.

6. Ember.js

Ember.js is functionally equivalent to Angular.js and React.js. Ember.js is extremely popular and new features are constantly emerging through its technical support community. Ember.js is similar to Angular.js in terms of data synchronization. This bidirectional data exchange mechanism ensures application speed and scalability. It also helps developers create front-end elements.

Similar to React.js, Ember.js also provides server-side virtual DOM to improve performance and scalability. Ember.js also encourages code reduction, provides excellent API options and has a great technical community.

7. Polymer.js

If you want to create your own HTML5 elements, you might want to try Polymer.js. At its core, Polymer extends development capabilities by providing Web developers with the ability to create their own tags. For example, you can create a tag and define functions similar to the

Polymer was launched by Google Inc. in 2013 under a 3-Clause BSD license.

8. Three.js

Three.js is another JavaScript library aimed primarily at 3D development. If you are an animator or game developer, Three.js is definitely worth a try. Three.js uses WebGL and can be easily used to render 3D objects on screen. You may have heard of HexGL, a futuristic racing game built by Three.js.

9. PhantomJS

Using JavaScript inevitably involves interacting with various browsers. When it comes to browsers, resource management is the most important issue. PhantomJS allows you to monitor Web application performance through its WebKit. This WebKit is also part of the rendering engine in Chrome and Safari.

The whole process is automated, and you just need to set up the Web application using the API it provides.

10. BabylonJS

BabylonJS and Three.js are similar in positioning, both providing JavaScript APIs to create powerful seamless 3D applications. It is open source and based on JavaScript and WebGL. The process of creating simple 3D objects such as spheres is very simple, requiring only a few lines of code. You can read BabylonJS's documentation carefully to understand the library's excellence. In addition, the project home page provides a number of inspiring excellent demonstrations.

11. Boba.js

There is one common requirement among Web applications, namely analytics. If you've been struggling with how to insert analytics into JavaScript apps, consider Boba.js. Boba.js helps you get things done easily and includes support for older ga.js. You can also use Boba.js to integrate metrics. The only prerequisite is jQuery.

12. Underscore.js

Underscore.js is the best solution for blank HTML editor files. When starting a project, many of my friends are faced with an empty screen and feel helpless or forced to repeat steps that have already been completed in previous projects. Underscore.js can provide several features based on this, such as allowing users to leverage their most commonly used Backbone.js or jQuery feature elements.

In addition, there are some functional help mechanisms, including "filtering" and "call graph", which are designed to help us get to work as soon as possible. Underscore.js also provides related suites to simplify the testing process.

13. Meteor.js

Meteor.js is a fast and efficient way to build JavaScript apps. It is an open source project and can be used to create applications for desktop, mobile and Web. Meteor.js is a full-stack framework for end-to-end development tasks on multiple platforms. Meteor.js allows you to create backend and front-end functionality and ensure that your app has excellent performance. Meteor.js also has a large technical community, so there are plenty of new features and bug fixes. Meteor.js is also naturally modular and works with a variety of excellent APIs.

14. Knockout.js

Knockout.js is clearly the most underrated option of all the frameworks mentioned today. This open-source JavaScript framework is based on the MIT license and builds on MVVM design.

15. Special recommendation: Node.js

Node.js is a powerful JavaScript runtime environment. It can be used to build high-speed and highly scalable applications with real data. It is neither a framework nor a library, but a runtime environment based on Google Chrome JavaScript V8 engine. Node.js allows you to create a variety of applications, including single-page applications, real-time Web applications, and more. Technically, Node.js's event-driven architecture supports asynchronous I/O, making it ideal for developing highly scalable solutions.

JavaScript is the universal language of the web. It has grown rapidly not only because of what it offers, but also because of the open source community around it. The frameworks and libraries mentioned above are must-check items for any JavaScript developer. They all provide ways to explore JavaScript and front-end development.
