Tooling

Code used in production is different from development code. In production, you need to build packages that run fast, manage dependencies, automate tasks, load external modules, and more. Tools that make it possible to turn development code into production code are called build tools.

webpack is a static module bundler for modern JavaScript applications. When webpack processes your application, it internally builds a [dependency graph](https://webpack.js.org/concepts/dependency-graph/) which maps every module your project needs and generates one or more bundles
