Is there anyway to combine these 2 regex patterns into one?

I have these 2 patterns, to remove multiple hyphens or underscores in a replace, and replace them with just one, but seeing as there, basically the same, I was curious if I could combine them into one pattern.

url = url.replace(/([-]+)/g, '-');
url = url.replace(/([_]+)/g, '_');

I believe the actual pattern would just be /([-_])/g, but I can't think how to tell if it should be replaced with a hyphen or underscore.

You can use a backreference:

url = url.replace(/([-_])\1+/g, '$1');

Pipe (|) operator is the OR function. Can you try this?

url = url.replace(/([-|_]+)/g, '-');
