parseInt alternative with characters in string

Question

If I have the following:

(8

Is there a way to get the number 8 out of it without splitting it? Using parseInt returns NaN. Is there an alternative to parseInt that ignores non-numbers?

You can use a quick regex to match that number, and just prepend + to cast to number:

var num =+ '(8'.match(/\d+/)
