Yarn is a Javascript package manager, serving as an alternative to NPM. It is an open-source project and was built by a team at Facebook. There are many advantages when using Yarn, such as:
- Offline Installation
- Faster download, packages are installed in parallel

As you can see, the interesting feature is the offline installation. Once you have installed a package, it will be cached and we can create another project from scratch without being connected to the internet, which in turn will save our bandwidth usage.
Usually, a project requires some dependencies and every time we install them to start a project, the “npm install” command would consume your bandwidth. When using Yarn, the download is done just once. Let’s begin installing Yarn.
