Does it have to be a regex? Or could you just do `str = str.substring(0, str.lastIndexOf(",") - 1);`? — jonhopkins, Feb 07 '13 at 18:22
@jonhopkins I know that lastIndex way, I want to do it with regex — Mithun Sreedharan, Feb 07 '13 at 18:24
@jonhopkins Why the "-1"? That would trim one more character before the last comma. Shouldn't it be `str = str.substring(0, str.lastIndexOf(","))` — whitehat, Mar 20 '18 at 21:13
