Javascript - Replace consecutive spaces with hyphen

Question

Can someone help me with replacing consecutive spaces with a hyphen? For example, I need:

123      321

to become

123-321

Thanks in advance!

var result = "123      321".replace(/ +/g, "-");
console.log(result);

/ +/g = at least 1 space, look globally (in the whole string)

The regular expression \s+ will match any number of consecutive spaces (including tabs and other whitespace characters). Use that as a global pattern for string.replace().

Example from a Javascript console:

> "a     b".replace(/\s+/g, "-")
"a-b"
