Is NaN always a falsy value in Javascript?

Question

console.log(typeof 3/0, Boolean(3/0)); // This returns NaN true
console.log(typeof 0/0, Boolean(0/0)); // This returns NaN false

I thought both will return NaN false in the Console as NaN is falsy value. But this is not happening. Can someone please explain this.

I used VS Code editor and Google Chrome Browser.

Try `typeof (3/0)`, as `3/0` actually gives `Infinity`, so the type is "number" (you're actually doing `(typeof 3)/0`) — Nick Parsons, Dec 13 '21 at 08:33

The result of 3/0 is Infinity (which is not NaN).

Infinity is a thruty value by spec.
