Switch versions of Node.js using Homebrew

# See node versions
brew search node

# Remove the existing symlinks
brew unlink node

# Install node at specific version
brew install node@12

# Link the new node install
brew link node@12 --force --overwrite

# To revert to node you need to
#   - unlink the specific install
brew unlink node@12
#  - force reinstall node because `brew link node` does not
#    re-link npm, apparently intentionally(?).

brew reinstall node

I've started using the n version manager which works in all shells, unlike nvm.

sudo mkdir /usr/local/n
sudo chown tillig /usr/local/n
n install latest
n list

Note the arrow keys in n don't work in PowerShell but you can use j and k to navigate instead, and that works fine.

I think if I was on Windows I'd probably use nvm-windows because, again, it's not shell-specific.
