Top 15 JavaScript Frameworks For 2024

#Why do we need JavaScript Frameworks?

JavaScript is the most widely used technology for developing web applications. It can be used on both frontend and backend for building full-stack applications. Many JavaScript frameworks simplify and streamline the development process.

These frameworks provide abstractions for routine development tasks, standardize formats for writing code - basically, what piece of code should go where in any production project, and use libraries built using the best practices.

Additionally, for frontend applications, these frameworks provide abstractions for different types of rendering, routing, and state management. They also ensure cross-browser compatibility. All in all, without these frameworks, developers would have to code everything from scratch, and it would take a lot of extra time and effort to build web applications.

In this article, we will explore various popular JavaScript frameworks for both frontend and backend.

#Frontend Frameworks

React

GitHub Link: React

React is a JavaScript library for building frontend applications.

React is not a production framework in itself and is more of a library. It enables developers to write reusable declarative UI components, manage data states, and provide interactivity. All of this would take a lot of time and effort if developers were to do it with pure HTML, CSS, and JavaScript.

React uses a virtual DOM that reduces the re-render time for views when the state changes and makes it highly performant. React can be used as a base for developing web or mobile applications.

Some of the key features of React are as follows:

Declarative Components - Declarative User Interfaces make creating interactive and dynamic React components easy.

Virtual Dom - React uses a Virtual DOM to manage changes to the state and the actual DOM.

JSX - React provides JSX, a syntax extension for JavaScript that lets you write HTM-like markup inside a JavaScript file.

Cross Platform - The same concepts of React can be applied while building mobile applications using React Native.

Pros and Cons:

Next.js is a battle-tested, production framework for React which is widely used for building full-stack web applications. Developers use the same React Components to build user interfaces, while Next.js supports additional features and optimizations.

Next.js provides a more structured approach to building React applications and standardizes how things should be done. Next.js also abstracts and automatically configures tooling needed for React, like compiling, bundling, and more. This allows developers to focus on building the application instead of spending time with configuration.

Some of the key features of Next.js are as follows:

Rendering - Next.js facilitates client-side and server-side rendering through Client and Server Components.

Data Fetching - Simplifies data fetching using async/await within Server Components.

Routing - Built-in file-system based router that supports nested routing, layouts, error handling, and more.

TypeScript - Next.js provides typescript support out of the box.

Optimizations - Next.js optimizes static content like Images, Fonts, and Scripts. This improves the User Experience and applications Core Web Vitals.

Svelte

GitHub Link: Svelte

Svelte is an increasingly popular technology that allows you to write declarative UI components. Svelte is the pioneer in rethinking how Reactivity works in frontend engineering.

Svelte does not employ a virtual DOM approach, rather the components are compiled into small, efficient JavaScript modules. This approach results in smaller bundle sizes, less JavaScript for the clients to download, and more benefits. This way many overheads that exist in other UI frameworks are eliminated in Svelte.

Svelte components are a combination of markup, styles, and behavioural logic. Svelte is incrementally adoptable, we can build our entire app with it or we can add it incrementally to an existing codebase.

Some of the key features of Svelte are as follows:

SvelteKit - SvelteKit is the recommended way of building Svelte Applications. If you're coming from React, SvelteKit is similar to Next. On top of Svelte functionalities, SvelteKit supports other pieces we need to build a web application, routing, SSR support, deployment, and more.

Compiler-Based Approach - Svelte does not use a virtual DOM like React or Vue, instead it compiles .svelte components into pure Vanilla JS. Due to this, Svelte apps are much lighter and more efficient.

Declarative Components - A component in Svelte is a reusable block of code in a .svelte file that contains HTML, CSS, and JavaScript. Svelte supports reactive declarations in the UI components.

Single-File Components - Svelte supports Single-File Components that allow us to encapsulate the template, logic, and styling in a single file.

Global Store & Animations - Svelte has out-of-the-box support for global state management and developers need not install additional libraries. Similarly, it has built-in support for creating smooth animations.

Pros and cons:

A few popular websites using Svelte in production:

• Brave Search
• Consensys
