I need a regular expression that matches any word containing, let's say, the sequence 'ab' exactly once. So it should match these:
- aaaabaaa
- ab
- abomination
and not these:
- something
- abab
- bacba
With my current regex \w*ab\w* I get all of the first list but also the second one of the second list as you can see in the snippet below. How can I specify that it should only match if it contains exactly one 'ab'?
let text = "aaaabaaa ab abomination something abab bacba",
console.log(text.match(/\w*ab\w*/ig));I searched for a while and didn't find a solution but if this is a duplicate of some kind please let me know and I will remove the question.
