Said no one ever. I can fully understand you not having Node installed (although having any kind of toolchain installed is a prerequisite for any programming so that's a weak argument against Node). But please don't tell me that somehow you will get an old version of Node after you just installed Node, because this is just reaching now.

The README that gets generated with the project literally spells out the correct command you should use to run the project during development (which is not `npm start`), so this argument is also pretty weak.
