What is nvm?
nvm can be defined as a Node Version Manager. It is a command line tool that helps web developers to manage and shift between their versions of node. Currently, nvm only works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.
Why use nvm?
Node evolves quite quickly. As a result, your old project that used the old node may not work as expected. It is super annoying to just switch different node versions for different projects in your local environment. Here nvm came and played a role to overcome this problem.
