Published: 2023-12-11 10:09:53

The [State of Developer Ecosystem 2022 report](https://www.jetbrains.com/lp/devecosystem-2022/) revealed that 65% of developers are using JavaScript, making it the most popular language. JavaScript also claims the spot of most popular primary language with 34%. Of all the JavaScript developers 80% use at least one JavaScript framework. Though there are thousands of JavaScript frameworks available, only a small subset of them is being used by developers. The popularity of frameworks depends upon several factors,  including: ease of use, relevancy, security, and flexibility. As more developers adopt a framework, a larger community is formed around it giving rise to its popularity.

In this blog post, we will discuss some of the best JavaScript frameworks. We also summarize the key points from each section into a comparison chart so that it's easy for you to pick the best framework based on your needs based on a few key considerations.

## What are JavaScript frameworks and why do we need them?

A JavaScript framework provides a supporting structure that we can use to build JavaScript applications. The structure offers a set of libraries and tools to aid the development and extension of an application's functionalities. Developing the same features in vanilla JavaScript yields equal results. However, a framework speeds up and simplifies the development process by providing built-in APIs, functions, and libraries. While frameworks offer flexibility, a good understanding of JavaScript fundamentals is essential to leverage their potential. 

As mentioned above, most of the developers use frameworks which means famous frameworks have a huge community. A community offers help and support along the development journey. 

Frameworks often provide cross-browser compatibility and security which offers an added advantage, helping developers focus on high-level functionalities. 

In summary, JavaScript frameworks act as accelerators streamlining the development process with added advantages. These advantages make them an essential part of a developer's toolkit.

## 12 Best JavaScript frameworks

### Frontend JavaScript frameworks

A frontend framework simplifies the development of client-side applications. The most prominent advantages of using frontend frameworks include reusable components, state management, and simplified event handling. There are hundreds of frontend frameworks available in JavaScript, here are some of the most popular: 

### 1.React

[React](https://react.dev/) is an open source frontend JavaScript framework developed by Facebook. [81.8%](https://2022.stateofjs.com/en-US/libraries/front-end-frameworks/) of survey respondents of the State of JavaScript survey use React for frontend development. It is a component-based framework specifically designed for single-page applications also known as SPAs.

**Key features:**

- **JSX:** JSX is an acronym for JavaScript XML which allows writing HTML in React components. JSX doesn't need creating or appending elements in the Document Object Model. Instead, we just need to write HTML and the elements get created by React itself.

- **Virtual DOM:** Virtual DOM is a copy of real DOM which gets updated whenever there is a change in application. Virtual DOM then compares itself with real DOM and only updates the changed part in real DOM. Since virtual DOM doesn't directly update the HTML structure, it improves the overall performance of the React application.

- **One-way data binding:** Data flows in one direction in a React application that is, from top to bottom. This means that a state change in parent component will trigger a change in child component. However, a state change in a child component won't automatically trigger an update.

**Pros** 

- **Reusable components:** React application consists of many components with separate logic. All the components can be reused multiple times which makes a React application easy to maintain.
  
- **Developer support:** React has a wide community of developers that plays a vital role in providing support and training resources to other developers. Additionally, its backing by Meta further enhances the strength of developer support.

- **Server-side rendering support:** Server-side rendering or SSR allows rendering a webpage on the server which improves page load speed and search engine optimization.

- **Stable ecosystem:** It's worth noting that React maintains a stable framework with infrequent changes. This ensures a seamless and reliable experience for developers.

**Cons**

- **Needs third-party libraries:** React can only handle the development and rendering of the UI components. Extra functionalities like routing, global state management, data fetching etc. require third-party libraries.
 
- **Difficult to get started:** React’s reliance on JSX for HTML embedding and Webpack can create a steeper learning curve for beginners compared to other frontend frameworks.
    
**Use cases and applications**

React is a versatile framework, widely used for the development of single page applications. Common use cases include complex and dynamic UIs, as well as mobile and realtime web applications. Famous companies using React include:

- **Facebook:** The clean UI structure you see on your Facebook feed is built using React. React keeps the sidebar, posts from friends, and new post input separated.

- **Instagram:** Like Facebook, Instagram is also built using React for the frontend. Component-based architecture makes Instagram fast and smooth to reload.

- **Netflix:** [Netflix chose React to develop its UI](https://netflixtechblog.com/netflix-likes-react-509675426db) because of its efficient performance and modularity.

### 2. Google Angular

Developed by Google, [Angular](https://angular.io/) is an open source TypeScript-based JavaScript framework. According to the State of JS survey, over [50%](https://2022.stateofjs.com/en-US/libraries/front-end-frameworks/) of respondents have Angular in their toolkit. Angular also offers a component-based architecture for the development of SPAs.

**Key features:**

- **Two-way data binding:** Two-way data binding refers to automatic UI changes when a data model is changed. This keeps developers from writing extra code to reflect data model changes to the UI.

- **Angular module:** Angular encapsulates related components, services, directives, and pipes together making it easier to maintain large applications. 

- **Built-in routing and forms:** Angular offers a built-in routing system and forms frameworks. This allows better control over form validation and routing.

- **Dependency injection:** Angular's dependency injection system offers easier object creation and management. Dependency injection allows enhanced code reusability and loosely coupled components.

**Pros**

- **Reusable components:** Like React, Angular also offers a component-based architecture which improves the application performance.
- **Server-side rendering support:** Angular applications support server-side rendering or SSR which provides optimized SEO support.
- **Large community and ecosystem:** Angular is backed by Google and has an active community of developers offering developer support, resources, tutorials, and additional libraries.
 
**Cons**

- **Steep learning curve:** Angular takes longer to get used to, especially for developers who aren't familiar with Typescript. Angular has way more aspects to unfold as compared to other frontend frameworks.
 
- **Frequently evolving ecosystem:** Angular is always under development to provide an improved developer experience. While a rapidly changing ecosystem resolves bugs, it is also challenging for developers to stay up to date.
 
**Use cases and applications**

Angular can be used to develop single-page applications (SPAs) and progressive web applications (PWAs). Companies using Angular include:

- **Google:** Google uses Angular for a number of its services including Gmail.
- **Upwork:** Upwork application is built using Angular including payment gateways and in-app conversation.

### 3. Vue

[Vue](https://vuejs.org/) is another one of the most popular frontend JavaScript frameworks. Vue is a progressive framework meaning,Vue provides core features and allows developers to choose additional modules as needed. This allows developers to start from the basics and add features as the application grows. [46.2%](https://2022.stateofjs.com/en-US/libraries/front-end-frameworks/) of respondents of the State of JavaScript survey have Vue under their belt, showcasing the framework's prevalence among JavaScript developers.

**Key features:**

- **Virtual DOM:** Like React, Vue also uses Virtual DOM which makes it time and performance efficient.

- **Reactive:** Vue is a reactive framework that automatically updates the UI when data changes.

- **Animations/ transitions:** Vue provides two built-in components that help apply animations or transitions to your HTML based on data/ state changes.

**Pros**

- **Easy to learn:** Vue doesn’t necessarily require a build tool and offers a syntax that resembles HTML. This makes Vue easier to learn as compared to other frameworks like React and Angular.
 
- **Reusable components:** Vue applications are component-based. Each component contains its own logic which can be used to develop a complex UI. 

**Cons**

- **Lack of enterprise backing:** Vue is a community driven project and is maintained by a developer community. Vue is not backed by any enterprise like React and Angular.

- **Lack of plugins:** Vue may not provide as extensive a range of plugins as other frameworks. This requires developers to write their own plugins which might be time consuming. 
 
**Use cases and applications:**

Vue can be used to develop component-based single-page applications. Companies using Vue include:

- **Apple:** [Apple developer documentation](https://madewithvuejs.com/apple-swiftui-tutorials) site is built in Vue.

## How to choose the best JavaScript framework?

Navigating the vast ecosystem of JavaScript frameworks can be overwhelming, especially for developers who are new to frameworks or do not have a strict tech stack requirement. We discuss a few considerations you might keep in mind to help you pick the best framework for your next project.

### Project requirements
Having a sense of possible complexities and requirements is crucial for picking the best framework. Project requirements might include size, complexity, nature of the project (frontend/ backend etc.), and performance. For example, if you need a fast backend server you might consider using Fastify, however, if you want an easier integration of realtime features you can pick Ably.

### Community support and documentation
A vibrant and supportive community is invaluable for assistance and support during the development process. There is barely any developer who doesn't run into strange bugs during development and communities help solve those bugs. For example, React and Express have a large network of developers however, Meteor lacks it.

### Common limitations
Every framework has its limitations and knowing them saves you a lot of time and cost in the long run. For example, Socket.IO provides a fallback mechanism but Sails doesn't. Compare framework limitations with your project requirements before making a decision.

### Flexibility
The ability of a framework to adapt to changing requirements and accommodate other technologies is another important consideration. There are frameworks that support only a certain frontend or backend technology.

## Conclusion
We hope this article served as a comprehensive guide for picking the best JavaScript framework based on your needs. By exploring some of the most popular frameworks and what makes them shine, we hope you’re equipped with necessary knowledge for thoughtful framework selection.
