Remove commas from Regex

I have the following JavaScript line of code that removes characters- including commas- from a string:

return str.replace(/(?!\/)(?!\ )(?!\-)(\W)/ig, '');

How can I only take out the piece of code that removes the commas?

The regex /(?!\/)(?!\ )(?!\-)(\W)/ig matches any character that is not a "word" character (ie. [a-zA-Z0-9_]) and the 3 lookaheads restrict also the character /, and -. The comma is removed because it is part of \W.

If you want to keep it, add another lookahead: (?!,), then your regex becomes:

return str.replace(/(?!\/)(?! )(?!-)(?!,)(\W)/g, '');

I've removed the unnecessay escape and the case insensitive flag.

This should be written as:

return str.replace(/[^\w\/, -]/g, '');
