Vagrant is a tool (or set of tools) to manage Virtual Machines.
Virtual machines allow you to run a completely different operating system, or even the same operating system within your current operating system. For example you could run Ubuntu within your Windows machine.

Why is this useful ?

Well there are 2 main reason. Standardization and reproduciblity.

Running code on a VM means you are using a standard system that others can use as well.
