Node Version Manager (NVM)
Why NVM ?
- Suppose you are core developer of Node Js who reviews code of many node js developers
- All the different applications code that you review might note be running on the same exact version of Node JS.
- So now you cannot re-install the Node Js everytime you encounter a new version so, NVM helps you to change the Node version as you please.
- There are many tools available on internet to manage node versions
- We are going to use NVM in our case
- Below is the link for documentation
- Run below command to install nvm
