Hey! fnm is a very simple and (very) fast node version manager. On my machine, `nvm init`/`nvm use` takes around 600ms - this means each time you spawn a new shell you have a ~600ms penalty.

The gif on the README is real time (it's a screen recording) - so installations are fast, and every command that works locally is extremely fast.

So, tl;dr, fnm is built with performance in mind
