When JavaScript is trolling you
I'll just test that it's ! isNaN() or isn't not a number when read literally, that will save me, I thought.

In JavaScript, false and 0 are not strict equally. Since it’s not a strong typed language, isNaN will considere 0 and return as false. Nowadays you can use isNumber to strictly check that. It’s safer.
Yes. What really made me want to throw a fit was when an empty string passed. I used isNumber()
LOL, no I didn't ...
