What is React JS?

React.js is an open-source JavaScript library for creating user interfaces for single-page applications. It handles the view layer for web and mobile apps. React also enables the creation of reusable user interface components. Jordan Walke, a Facebook software engineer, was the first to create React. React was first used in the Facebook newsfeed in 2011 and on Instagram in 2012.

React.js is popular for its user-friendly interface and is frequently used in web development even though it is not a programming language. It makes use of JSX for templating as opposed to standard JavaScript. JSX is a straightforward JavaScript that supports HTML (Hypertext Markup Language) quoting and renders subcomponents using this HTML tag syntax. React Framework JavaScript calls are generated from HTML syntax. We can also use the original JavaScript language.

How to Learn React JS?

There are many readily available opportunities for learning react.js. These include:

  • Upskilling or reskilling through online React courses, including the official tutorial from React
  • Attending webinars and discussions on the fundamentals of React as well as its future
  • Going back to the basics of HTML and reigniting your interest in Javascript

What Skills Are Related to React JS?

While advanced knowledge of coding isn’t compulsory, one should be at least somewhat familiar with the following concepts before pursuing structured react courses:

  • Functions, objects, arrays, and classes, among other programming concepts

  • Working knowledge of HTML and some JavaScript

What is React Used For?

  • Easy development of dynamic applications: React simplifies the development of dynamic web applications by requiring less coding and providing more functionality than JavaScript, where coding can quickly become very complex
  • Web application development: Working with the DOM application programming interface (API) is challenging. In essence, React enables developers to work with a friendlier virtual browser than the real browser. The virtual browser in React functions as an intermediary between the developer and the real browser.
  • Enhanced web performance: React uses a virtual document object model (DOM) to create web applications swiftly. In contrast to traditional web applications, which update all components again, Virtual DOM compares the previous states of the components and updates only the items in the Real DOM that have changed
  • Developers can model the state of their User Interfaces and declaratively describe them using React. This means that developers should only describe interfaces in terms of a final state rather than creating steps to describe transactions on them (like a function). React updates the User Interfaces based on transactions that affect that state.

What Jobs use React JS?

According to Statista, 40.41 percent of software developers worldwide say they use React JS to create web applications, making it the most in-demand web framework in 2022. Evidently, the demand for the tool is high. Let’s list down the jobs that use React JS:

  • React developer

  • Front-end developer

  • Mobile app developer

What is the difference between React Native and React JS?

React is not a complete framework and relies on various libraries to provide an all-around front-end development utility. React JS is the umbrella framework for creating dynamic web and mobile applications. React Native, on the other hand, is a React JS-based framework for designing mobile apps. It is a hybrid mobile app framework that allows it to create mobile apps from a single codebase. With the help of this JavaScript framework, you can create mobile applications that work seamlessly on iOS and Android. Where React JS uses a Virtual DOM, React Native relies on Jave APIs and Objective-C.
