How to remove all extra spaces, js?

Question

JavaScript

Good afternoon! Can you please tell me how to remove all extra spaces?
For example, there is a line

const str = ' some     string  and        something  '

the result should be
const str = 'some string and something'
at the moment stopped at this, but it does not work as it should.
const reg = /(^\s+|\s+$)|\s\s+/g;
I would be grateful for the help!

Answer 1

str.replace(/\s+/g, ' ').trim()
