alt Hacker NewsMaybe it's just me, but it seems like a huge waste of time (or to be on a more positive note - potential).
Just the first example "Device type in JS".
"A coarse pointer does not mean “mobile”, and a fine pointer does not guarantee “desktop”. Ask the browser about input capabilities instead of guessing the device from its user agent."
const input = {
finePointer: matchMedia('(any-pointer: fine)').matches,
coarsePointer: matchMedia('(any-pointer: coarse)').matches,
canHover: matchMedia('(any-hover: hover)').matches,
};

It has all the hallmarks of just telling an agent to scrape MDN and make a website

You’re right: it doesn’t identify the device type, so the title is misleading.
The intended point is that device type is often the wrong thing to detect: a touchscreen laptop may expose both coarse and fine pointers, while a tablet may be connected to a mouse or trackpad. The snippet detects available input capabilities instead, which is usually what the interface should respond to.
I wasn’t particularly careful with the titles, but this one should be "Detect input capabilities". Thanks for the heads-up!
