Dependency Graph
Any time one file depends on another, webpack treats this as a dependency. This allows webpack to take non-code assets, such as images or web fonts, and also provide them as dependencies for your application.
When webpack processes your application, it starts from a list of modules defined on the command line or in its configuration file. Starting from these entry points, webpack recursively builds a dependency graph that includes every module your application needs, then bundles all of those modules into a small number of bundles - often, only one - to be loaded by the browser.
