How to replace all spaces present in a string with underscore using javascript?

Question

I have a string with spaces separating words. I want to replace all the spaces in the string with underscore. Please tell me any small code for that because my solution is taking too much space. Example : 'Divyanshu Singh Divyanshu Singh' output : 'Divyanshu_singh_Divyanshu_Singh'

`yourString.replace(/\s+/g, "_")` – Scott Marcus Jun 01 '18 at 12:14 — Scott Marcus, Jun 01 '18 at 12:14

Try this one:

    var str = "Divyanshu Singh Divyanshu Singh";
    var res = str.replace(/ /g, "_");
    console.log(res);

Use, / /g is a regex (regular expression). The flag g means global and causes all matches to be replaced.

will only replace the first match. – Aniruddha Gohad Jun 01 '18 at 12:17
`/ /` won't find multiple spaces in a row. It should be: `/\s+/g`. – Scott Marcus Jun 01 '18 at 13:12
