Yarn is a package manager. It lets you install libraries and run scripts for JavaScript.
If you need to add a library to your project you do something like 'yarn add react' for example. That would install react in your project.
If you write code that needed to be compiled or you wanted to minify it or change it in some way you can also use yarn to help.
