React JS

Introduction

Currently, ReactJS gaining quick popularity as the best JavaScript framework among web developers. It is playing an essential role in the front-end ecosystem.

What's more, its popularity is growing as it's supported by Facebook and a vibrant community. React.js is a dominating frontend JavaScript technology, and it's getting more and more popular. According to GitHub, over the last few years, the number of React.js package downloads with NPM vs. the other two popular frameworks - Angular/Core and Vue - has accelerated significantly. Technology use spreads with power laws and it looks like React.js is taking over its category.

React.js framework it's a tool to build UIs - a JavaScript library for building user interfaces. Some software engineers prefer not to call it a "framework" since it gives the developers much more freedom than Angular or Vue.

Just like Angular is supported by Google, React.js is maintained by Facebook and a community of developers. Both are open source and free to use under the MIT license. React.js is only six years old, which makes it a relatively new technology. However, it matured very quickly. /p>

What is React JS?

React is an open-source JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React makes it painless to create interactive UIs. You can design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.

ReactJS is a JavaScript library that combines the speed of JavaScript and uses a new way of rendering webpages, making them highly dynamic and responsive to user input.

The product significantly changed the Facebook approach to development. After the library was released, it became extremely popular due to its revolutionary approach to programming user interfaces setting the long-going competition between React and Angular, another popular web development tool.

It is a powerful library that is optimal for fetching data which is rapidly changing. Its main function is data rendering. The DOM of the web page is what the ReactJS targets. But what makes it most efficient is that it does not update the whole web page, instead, it only updates the part of the DOM which is changed.

Objective of this Training

ReactJS offers graceful solutions to some of front-end programming’s most persistent issues, allowing you to build dynamic and interactive web apps with ease. It’s fast, scalable, flexible, powerful, and has a robust developer community that’s rapidly growing. There’s never been a better time to learn React.

React is very popular. As a developer, it's quite likely that you're going to work on a React project in the future. Perhaps an existing project, or maybe your team will want you to work on a brand-new app based on React. A lot of tooling today is built using React at the core. Popular frameworks and tools like Next.js, Gatsby, and many others use React under the hood.

As a frontend engineer, React is probably going to come up in a job interview. Those are all good reasons, but one of the main reasons I want you to learn React is that it's great.

It promotes several good development practices, including code reusability and component-driven development. It is fast, it is lightweight, and the way it makes you think about the data flow in your application perfectly suits a lot of common scenarios.
