Agreed, which makes it all the more useful to know that it's classified as one in JS anyway (and in fact by most other software and runtimes too, due to the IEEE 754 standard for floating-point arithmetic).
The isFinite global function (spec, MDN) might come in handy next time you need to validate a numerical type.
At the risk of sounding super pedantic, it would be more accurate to say infinity represents a number (a quantity) rather than actually being one itself. Unlike maths' infinity which can actually represent different measures, JS' version is essentially just an "out of bounds" indicator (x+n) within our "fake" digital/binary arithmetic and therefore only infinite on a philosophical level.
Funny when you realise that JS' infinity is actually, at its most basic level, a very much finite amount of ones and zeroes.

We're a place where coders share, stay up-to-date and grow their careers.
IMO infinity is not a number.
Yes
Well, in JS it is a number.
maybe calling it Infinity was a poor choice 😉
