Creating a Toolchain from Scratch

A JavaScript build toolchain typically consists of :

A package manager, such as Yarn or npm. It lets you take advantage of a vast ecosystem of third-party packages, and easily install or update them.
A bundler, such as webpack or Parcel. It lets you write modular code and bundle it together into small packages to optimize load time.
A compiler such as Babel. It lets you write modern JavaScript code that still works in older browsers.
