## What it is
n is a simple BASH script for managing and switching between Node.js versions on macOS, Linux, and other unix-like systems. It installs, selects, and removes Node.js versions without subshells or profile setup.

## Use cases
- switch between node versions
- install a specific node.js version
- manage multiple node versions on linux
- upgrade node to latest lts
- remove old node versions
- pin node version for a project

## When to choose
- you want a minimal, no-subshell node version manager on macOS or Linux
- you prefer a single bash script over nvm's shell functions
- you need quick interactive switching of node versions

## When to avoid
- you are on native Windows shells like PowerShell, Git Bash, or Cygwin
- you need per-shell automatic version switching based on project files
- you need to manage other runtimes besides Node.js

## Facets

- function: cli, developer-tools, package-manager
- domain: developer-tools, version-control
