 `npm run build` creates a `build` directory with a production build of your app. Inside the `build/static` directory will be your JavaScript and CSS files. Each filename inside of `build/static` will contain a unique hash of the file contents. This hash in the file name enables [long term caching techniques](#static-file-caching).

+When running a production build of freshly created Create React App application, there are a number of `.js` files (called _chunks_) that are generated and placed in the `build/static/js` directory:

-- This is your _vendor_ code, which includes modules you've imported from within `node_modules`. One of the potential advantages with splitting your _vendor_ and _application_ code is to enable [long term caching techniques](#static-file-caching) to improve application loading performance. Since _vendor_ code tends to change less often than the actual _application_ code, the browser will be able to cache them separately, and won't re-download them each time the app code changes.
