Yeah, this is the answer. TBH..... you should get over your fear of npm. If you already have node installed you can just run npm i -g typescript ts-node

This will give you tsc as a global command line to compile typescript to javascript.

ts-node is optional, but it is the standard node cli that can run typescript

After you install these two you can just ignore that you have npm forever.

(... but yes you can also just download the js file as the person above suggested if you're really stuck on being anti-npm)
