What is ReactJS?

ReactJS is a free, open-source front-end JavaScript library that builds user interfaces based on UI components. It is maintained by Meta and a community of developers. React can be used to create single-page, mobile, or server-rendered applications with frameworks such as Next.js. However, React is only concerned with handling state and rendering it to HTML, so creating React applications usually involves integrating routing libraries as well as client-side functionality.

 

Features

Declarative
Creating interactive UIs is easy with React. With simple views for every state in our application, React will update and render the appropriate components as our data changes. Code with declarative views is more predictable and easier to debug.

Component-Based
Build components that manage the state on their own, then compose them to create complex UIs. Because component logic is written in JavaScript, we can pass rich data through our app and keep state out of the DOM.

Learn Once, Write Anywhere
No assumptions are made about the rest of the technology stack, so we can develop new features in React without rewriting existing code. React can also be rendered on the server using Node and power mobile apps using React Native.

 

History

React was created by Jordan Walke, a software engineer at Facebook, who released an early prototype called “FaxJS.” He drew inspiration from XHP, a PHP component library that is based on HTML. The platform was first deployed on Facebook’s News Feed in 2011 and later on Instagram in 2012. It was open-sourced at JSConf US in May 2013.

React Native, which allows native Android, iOS, and UWP development with React was announced at Facebook’s React Conf in February 2015 and open-sourced in March 2015. With version 15, React.js started using Semantic Versioning. In addition, this helped convey to the developer’s community that React was more stable.

A large number of Fortune companies currently use React.js. Facebook has a dedicated React development team. This team releases updates, enhancements, blog posts, and documentation regularly.

 

Advantages of ReactJs

React.js is a popular JavaScript library for developing Web applications on the front end. A large number of web applications can be created using it since it is fast, scalable, simple, and highly advantageous for changing data without reloading the page. Following are the advantages of ReactJS.

Handy and Powerful Javascript Library: It is a library of reusable code that developers use to create user interfaces (UIs) for web applications, mobile apps, and websites.

Developers can reuse components multiple times with React. Instead of writing repetitive code, they can use React libraries to find shortcodes built by other developers, incorporate them into their workflow, and get on with other coding tasks.

SEO friendly: The goal of SEO is to make it easier for developers to find relevant content for users. Whenever a user performs a search, search engine platforms like Google, Yahoo, Bing, or Baidu try to determine which page is most relevant to that search. A SPA (Single Page Application) provided by React can affect SEO because Javascript is needed to display the content on the page so that it can be indexed and indexed.

Components Support: ReactJS is a combination of JavaScript and HTML. Using HTML tags and JS codes, it becomes easier to handle a large collection of data containing the document object model. As a mediator, ReactJS represents the DOM and determines which component needs to be changed to get the desired result.

Proficient Data Binding: ReactJS excels at two-way data binding. Anyone can therefore track all the changes made to a particular segment of data. That is an example of its simplicity.

Fast, efficient, and easy to learn: It contains pre-built patterns and functions that can be combined and selected as building blocks to create fast, appealing, and scalable projects in less time compared to designing each line by line. Unlike Angular and Ember, which are called ‘Domain-Specific Languages’, React only requires a basic understanding of HTML and CSS fundamentals to start using it.

 

Career in ReactJS

Developing a career in web developing, freelancing, or working remotely for a company is a good choice. Developers of React JS are in high demand and the number of jobs is growing. React developers are needed in all industries and geographies. In recent years, due to its extensive nature, ReactJS has gained a lot of popularity among the world’s tech companies. We will need to learn more than just React JS skills to be successful in our careers.

 

Conclusion

The React library provides a powerful tool for creating interactive applications for mobile, web, and other platforms. Because of React’s popularity and usage, it keeps growing every day. Developers who code in React are better at JavaScript, a language that holds nearly 90% of the market share.
