Truncate sentence to a certain number of words

Question

How can a sentence be truncated to a certain number of words (NB. not letters)?

I thought to use split(" "), but then how do I count out words?

For example:

• Javascript word count cut off => Javascript word count
• Want better search results? See our search tips! => Want better search

Answer 1

You can use split ^[MDN] and join ^[MDN].

"Want better search results? See our search tips".split(" ").splice(0,3).join(" ")
