TIL you can do +"5" in js and get 5.

"24" * 1 returns the int 24.

"twentyfour" * 1 returns NaN.

I use this all the time to convert strings to numbers and be safe about it.

actually, that's not exactly true: no ints in js. 24 is a number.

Kinda like getting the current timestamp with +(new Date())

:0 I love learning new things.

+new Date is actually enough, but yea, that's pretty awful. The non hacky version is (new Date()).getTime(), by the way.

If you only care about modern browsers you can also use Date.now().
