Your browser then sends a request for that webpage, which your browser renders.

Typically, you request a webpage by typing its URL into your web browser. Due to its revolutionary approach to DOM manipulation and user interfaces, React dramatically changed Facebook’s approach to web development and quickly became popular in JavaScript’s ecosystem after its release to the open-source community.

React simplified the development process by providing a more organized and structured way of building dynamic and interactive user interfaces with reusable components.įacebook’s newsfeed used it first. Jordan Walke, one of Facebook’s software engineers, created React to do just that. It wanted to offer users a richer user experience by building a more dynamic and more responsive user interface that was fast and highly performant. In doing so, the ReactJS framework combines the speed and efficiency of JavaScript with a more efficient method of manipulating the DOM to render web pages faster and create highly dynamic and responsive web applications.īack in 2011, Facebook had a massive user base and faced a challenging task. Rather than dealing with the whole user interface as a single unit, React.js encourages developers to separate these complex UIs into individual reusable components that form the building blocks of the whole UI. React’s primary role in an application is to handle the view layer of that application just like the V in a model-view-controller (MVC) pattern by providing the best and most efficient rendering execution. These components are individual pieces of a final interface, which, when assembled, form the application’s entire user interface. In React, you develop your applications by creating reusable components that you can think of as independent Lego blocks. It’s used for building interactive user interfaces and web applications quickly and efficiently with significantly less code than you would with vanilla JavaScript. The React.js framework is an open-source JavaScript framework and library developed by Facebook. For those who are new to web development, or trying to figure out what all the fuss is about, let’s look at React, how it works, and what makes it different from other JavaScript frameworks.
