JavaScript parse int from string

Question

I have string: "You can vote 36 times for topics and 84 times for comments".

I need to get number 84 from string (number can be different).

How can I do it?

Ah there is good number of what-have-you-tried-Guys here, noobs and beginners, no luck for you guys. Say thanks to @qwertymk who is NOT what-have-you-tried-Guy like me :) — Blaster

@Blaster: Asking does not hurt anyone. Even an answer such as "I don't have any idea how to approach this" might give some idea about the level of knowledge. — Felix Kling

@Blaster: When I commented, qwertymk already provided is answer, so that's more likely to be the reason that one else answered. It's a reminder to include any related research effort. Granted, this question did not necessarily need it, but I rather comment one time too often than not enough. — Felix Kling

Try this:

/^You can vote \d\d times for topics and (\d\d) times for comments$/.exec(str);

Or:

/^You can vote \d+ times for topics and (\d+) times for comments$/.exec(str);
