Only one occurence of the symbol in string - regexp

Question

I have a string like that:

var x = _something_ somethingelse _whatever_

I'd like to match by regular expressions only something and whatever words (because they are located between two underscore characters directly). Rest word is between underscore characters by accident - I don't need it. The regular expression I use is matches all of them. How to fixed that? My curent regexp:

/_(.*)_/gm

Answer 1

You could search for a word boundary and then for underscore.

var x = '_something_ somethingelse _whatever_ foo_bar _foo_2';

console.log(x.match(/\b_[^_]+_\b/g));
