How do I install multiple node js version on the same machine

In this post, we will get to know and learn about running multiple node js version on the same machine with NVM .

While working on the multiple projects of NodeJs, you might be required to run different projects on the different nodejs version or for the legacy nodejs projects, you might require an old version of the nodejs, and the others required a new version of node-js, or to checkout the new feature of nodejs, you need to install the latest version of node js

As on the same machine, we can only install one version of the nodejs, so it's very painful to uninstall and install the new node version as per your project requirements.

To overcome this problem, we can use the Node Version Manager (NVM). NVM allows installing multiple node js versions on the same machine and switching between the required node js version.
