webpack creates a graph of all of your application's dependencies. The starting point of this graph is known as an entry point. The entry point tells webpack where to start and follows the graph of dependencies to know what to bundle. You can think of your application's entry point as the contextual root or the first file to kick off your app. Simple rule: one entry point per HTML page. SPA: one entry point, MPA: multiple entry points. Entry Points are also called chunks
