For instance, running an app that relies on an older version of NodeJS.
NVM is a NodeJS version manager that makes it possible to do just that.

Installing a specific version of NodeJS
Let's say we would like to install version 12 of NodeJS. We would run the following command to do so:
01: nvm install 12
Once you have different versions of NodeJS installed you can switch between them using the command below:
01: nvm use 12
You can also check which version of NodeJS you are running at any point in time:
01: node -v
