# Top 10 JavaScript Frameworks Soha Rajput JavaScript, first developed for Netscape Navigator in 1995, is a dynamic programming language. It has now been accepted by all major browsers as a standard method for enhancing the functionality of web pages and, more recently, online applications. The years since JavaScript's development have allowed it to mature into a robust programming language. Its once-exclusive web use has expanded to include virtually every other environment, even outer space. JavaScript was never intended to become the backbone of today's web development. Actually, it took less than two weeks to develop the language, and it was originally intended for something else entirely. Today, among 1.8 billion websites in the world, approximately [98% of websites use JavaScript](https://w3techs.com/technologies/overview/client_side_language) as a client-side programming language, which shows its increasing popularity. ## What is JavaScript Framework? A JavaScript framework is a group of JavaScript libraries that web developers can use to save time by using code that has already been written. Users can make strong web apps without JavaScript frameworks, but it can be very helpful to use tools like a template that handles basic programming patterns. When you use frameworks to build an app, you don't have to write the same code for the same features over and over again. Instead, you can take those features out of the framework libraries and keep going. JavaScript is known to be one of the most popular languages for both front-end and back-end web development. The JavaScript framework gives developers a head start with a lot of ready-made modules and features they need to make JavaScript apps. JS has broken new ground when it comes to making dynamic websites and web-based apps. The foundation is provided by JavaScript, and the JS frameworks are used to make things look nice. ## Why Do Developers Love JavaScript Framework? Unlike any other programming language, it was built with model/view separation in mind. Object-Oriented Programming ideas are easy to use and are familiar with JavaScript, which is used for web programming. It adds a lot of dynamic features to web pages and makes them easier to use and more interactive. Creating web apps and websites can take time from the beginning to the end. But JavaScript frameworks use the fact that most websites and web apps have the same set of properties to their advantage. JavaScript frameworks run pre-written JavaScript code that makes routine programming features. This makes the whole development process much easier. Stack Overflow conducted a developer survey in 2022 to explore more about tools developers use, how they learn them, and what they think about them. The survey found that JavaScript was the language that was used the most. ## Top 10 JavaScript Frameworks ### 1. Node.js Node.js is an open-source, cross-platform JavaScript runtime environment for servers. The event-driven framework can be used to drive asynchronous I/O. It's compatible with the JavaScript Runtime and demonstrates JAVA-like characteristics, including threading, packing, and loop formation. One of the most widely used implementations of server-side JavaScript is called Node.JS, or simply Node. Large-scale platforms for organizations like NASA and eBay have been written in Node. Node can take advantage of Javascript's ability to run code in a non-deterministic order to build scalable web apps, chat systems, and multiplayer games. For this reason, Node is also utilized by both Google Cloud and Amazon Web Services. **Features:** - Single-threaded: Operated on Single Threaded Event Loop Model architecture. - Asynchronous: Allows parallel programming. - Event-driven: User events, such as mouse clicks or keypresses, can execute programs. - NPM: The Node Package Manager, also known as NPM, is the most comprehensive online repository for the Node. ### 2. React.js With Facebook's release of the ReactJS framework, interest in JavaScript skyrocketed. Its JavaScript library is praised by programmers for being declarative, efficient, and open source, making it ideal for creating dynamic, feature-rich, and user-friendly front-end web applications. **Features:** - Declarative: Makes websites and mobile apps with interactive and dynamic user interfaces (UI). - Virtual DOM: Every DOM object has a "virtual DOM object" that makes a virtual copy of the original DOM and acts as a DOM object's representation. - Handling events: React has an event system that works with the W3C object model and is fully compatible with it. - JSX: JSX is a syntax for markup that is similar to HTML. ### 3. Angular.js AngularJS is the best when it comes to making single-page applications. Web developers prefer AngularJS over other development frameworks because it puts a lot of emphasis on code quality standards. Angular.js is used by top companies like Snapchat, Gmail, Amazon, Udemy, and Forbes to build their websites. **Features:** - Progressive Web Apps: Uses modern web platform features to provide app-like experiences that work well offline. - Code Generation: Turns templates into optimized code for JavaScript virtual machines. - Code Splitting: The new Component Router makes it easy for Angular apps to load quickly by automatically splitting the code. ### 4. Vue.js It's safe to say that Vue is the most flexible JavaScript framework out there right now. Furthermore, it is the most accessible framework for both programmers and non-programmers alike. Vue is flexible and simple enough for non-experts to use. **Features:** - Virtual DOM: Utilizes a virtual DOM, a clone of the principal DOM element. - Data Binding: Makes it easier to change the values of HTML attributes or give them new values. - CSS Transitions and Animations: Several ways to add a transition to HTML elements when they are added, updated, or removed from the DOM. ### 5. Ember.js Ember.js is a powerful open-source JavaScript/HTML5 MVC application framework. Ember.js is recommended for projects that need a web app with an interface and feel like a desktop app, along with a single-page website. **Features:** - HTML and CSS: Core of development model. - Routes: Used to handle the URL. ### 6. Meteor Meteor can be used in many different ways, including back-end development and database management. It is an isomorphic framework made with Node.js. **Features:** - Full-Stack Solution: For building and deploying web applications. - Isomorphic JavaScript Code: The same code can be used on both front-end and back-end. ### 7. Polymer.js Polymer.js simplifies and speeds up the creation of web applications by providing reusable building blocks. **Features:** - Reusability: Used to make widgets that can be reused in web documents and apps. - Flexibility: Custom elements can be used with HTML Imports. ### 8. Backbone.js Backbone.js makes it easier to manage and update your JavaScript code. **Features:** - Single-threaded: Uses an event mechanism that doesn't block other requests. - Open source: The community has developed many models that add features to Backbone.js applications. ### 9. Aurelia Aurelia is a cutting-edge open-source UI framework, ideal for creating both online and mobile applications. **Features:** - Web Standards: Emphasizes clean code. - Extensible: Easy to connect to other tools. ### 10. Mithril.js Mithril is a client-side JavaScript framework used for creating Single Page Applications. **Features:** - Small API: No need to build functionality for every possible case. ## Bottom line Now that you know about the top 10 JavaScript frameworks, think about the context in which you'll be deploying the framework before choosing one. The next step is to educate yourself on the framework's intricacies and functionalities. ## Top JavaScript Frameworks: FAQs ### 1. How many different JavaScript frameworks are there?
