Only reason I’ve ever used it was for TS but as far as I know that’s a different concept from the JS void operator

Technically you can capture the value of a method with no return and you'll have a void.

Compares truish to null and true to undefined.

When I was younger and wiser I used to return void 0, instead of not returning anything. 🤣

It was mainly to annoy other people.

@eo2875 Mostly in TS context, but there are some uses for it in plain JS too.

Extremely rare though, but you said "EVER" and the answer is yes. :)
