Webpack is a JavaScript tool used to bundle all of the assets and code needed to run a web application. It takes all of the individual files and modules that make up an application and compiles them into one file or a few files that are optimized for the web. It also has features like code splitting, which helps to reduce the size of the final bundle and improve performance.Webpack is a JavaScript tool used to bundle all of the assets and code needed to run a web application.
