Tell Webpack where your application starts so it knows what to build.
An entry point is where Webpack starts looking at your application. You give Webpack one or more starting files, and it follows the imports from those files to discover the rest of the code your application needs.
Understanding entry points is important because they define the beginning of Webpack's dependency graph. Simple applications may have one entry point, while larger applications can use multiple entry points for things like separate pages or bundles.
