Javascript - Yarn

Yarn is a package manager

It aims to resolve two problems:

• to download the library only once by having a local repository
• to fix the code of the dependency. Library authors may have change the code without changing the version and break your code. The immutability of installed packages is handled via a yarn.lock file, which ensures that every install results in the exact same file structure in the node_modules across all machines.

Most yarn commands are similar to npm equivalents and it is fine to use the npm versions instead
