React is one of the most popular front-end JS (JavaScript) library for building User Interface (UI) components. It was developed and is being maintained by Facebook along with a community of developers, and companies. Now Webpack comes into the picture, in today’s time, where applications are being built keeping in mind the end-user experience, and everyday new styles and layouts are being created that is smooth and enhances the user-interactivity to a higher degree. All of this is possible, only by using various types of resources, libraries, etc. to create one application or web page. But the real problem was that the modern-day computer browser has not yet supported these high-level languages, or libraries, as a result, you would need a solution for the problem, and that is Webpack.
Webpack allows you to bundle your applications or web page in a language that your browser will work. If you wish to learn React JS, then check out the React certification course, from Intellipaat. Also, have a look at our YouTube video on ReactJS for Beginners.
