In 2021, there are several front end developer technologies that you should learn to enhance your skills and increase your career prospects. This article will explore the top front end developer technologies you need to learn in 2021.

1. React.js:
React.js has been gaining immense popularity among front end developers over the past few years. It is a JavaScript library developed by Facebook, which allows you to build reusable UI components. React.js follows a component-based architecture, making it easier to create complex user interfaces. Learning React.js can open up numerous job opportunities as it is widely used in the industry.

2. Angular:
Angular is a powerful JavaScript framework developed by Google. It is known for its ability to build dynamic and scalable web applications. Angular follows the MVC (Model-View-Controller) architecture, which makes it easier to organize your code. It also offers a wide range of features, such as dependency injection, two-way data binding, and routing. Learning Angular can give you an edge in the job market, especially if you are interested in working on large-scale enterprise applications.

3. Vue.js:
Vue.js is another popular JavaScript framework that has gained significant traction in recent years. It is known for its simplicity and ease of use. Vue.js allows you to build interactive user interfaces with minimal effort. It also offers features like component-based development, reactivity, and a virtual DOM. Learning Vue.js can be a valuable addition to your skill set, as it is being adopted by many companies as their go-to front end framework.

4. TypeScript:
TypeScript is a superset of JavaScript that adds static typing and other advanced features to the language. It helps in catching errors during development and improves code quality and maintainability. TypeScript is widely used with frameworks like Angular and React.js. Learning TypeScript can make you a more efficient and reliable front end developer, as it enables you to write safer and more robust code.

5. GraphQL:
GraphQL is a query language for APIs and a runtime for executing those queries. It provides a more efficient and flexible way to fetch and manipulate data from the server compared to traditional REST APIs. With GraphQL, you can request only the data you need, reducing the amount of network traffic and improving performance. Many companies are adopting GraphQL as their preferred data-fetching solution, making it a valuable skill for front end developers.

6. Next.js:
Next.js is a popular React framework that helps in building server-side rendered and static websites. It provides features like automatic code splitting, server-side rendering, and static site generation, which can significantly improve the performance and SEO of your web applications. Learning Next.js can give you an advantage in developing high-performance websites and improve the user experience.

7. Tailwind CSS:
Tailwind CSS is a utility-first CSS framework that allows you to build custom and responsive user interfaces quickly.

Tailwind CSS promotes a mobile-first approach and gives you complete control over the design of your application. Learning Tailwind CSS can help you build modern and visually appealing user interfaces with less effort.

8. WebAssembly:
WebAssembly is a binary format that allows you to run high-performance code on the web. It enables you to write applications in languages like C, C++, and Rust, and compile them to run in the browser. WebAssembly has the potential to revolutionize web development by providing near-native performance and opening up possibilities for porting existing applications to the web. Learning WebAssembly can give you a competitive advantage in developing high-performance web applications.

9. Progressive Web Apps (PWA):
Progressive Web Apps are web applications that use modern web capabilities to provide an app-like experience to users. PWAs can be installed on the user’s device and can work offline. They offer features like push notifications, background sync, and access to device hardware. Learning to develop Progressive Web Apps can make you a versatile front end developer, capable of building web applications that function seamlessly across different devices and platforms.

10. Jamstack:
Jamstack is a modern architecture for building websites and web applications. It stands for JavaScript, APIs, and Markup. Jamstack promotes the use of static site generators, pre-rendering, and serverless functions. It offers benefits like improved performance, scalability, and security. Learning Jamstack can give you a competitive edge in developing modern and efficient web applications.

In conclusion, front end development is a rapidly evolving field, and staying updated with the latest technologies is crucial for your career growth.
