What is the NVM
๐ NVM is a node versioning tool that allows you to install multiple Node versions (and matching NPM versions) in the same environment and switch between them at any time.
Ordinary computers can only install one version of Node ๐, but in work, we may use different versions of Node in face of different projects, which caused a lot of trouble to programmers ๐จ๐ป. At this time, NVM came into being ๐ฝ
