Developer tool
What it does
A shell script that installs several Node.js versions side by side and switches between them per shell or per project through an .nvmrc file.
Adopt it when
You work on macOS or Linux across projects pinned to different Node.js versions and only need to manage Node itself.
Watch out
It does not run on native Windows (that needs the separate nvm-windows project), and loading it in every shell adds noticeable startup time.
