Regex to remove all whitescape except one between words?

Question

Simple as the title, really.

Is there a Regex expression to remove all whitespace except one between words.

So

"  Hello. How   are  you     today?    "

would become

"Hello. How are you today?"

Answer 1

This will do what you wish:

"  Hello. How   are  you     today?    ".replace(/\s{2,}/g,' ').trim()
