Remove all global npm packages

Bash Shell

npm r -g $(node -e "console.log(process.argv.filter((e) => e !== '├──' && e !== '└──').filter((_, i) => i > 1).map((e) => e.split('@')[0]).filter((e) => e !== 'npm').join(' '))" $(npm list -g -depth 0))

Fish Shell

npm r -g (node -e "console.log(process.argv.filter((e, i) => e && i > 1).map((i) => i.split(' ')[1].split('@')[0]).filter((i) => i !== 'npm').join(' '))" (npm list -g -depth 0))

A simple script that removes all npm packages. This was tested on macOS using both Fish & Bash shells.
