Looking for possible regex solution, since I still suck at it. The goal of the regex is to validate if string fits the format. First should be random length string, then comes colon (:) and the last is one of two options: desc or asc. someString:desc|asc Examples: firstName:desc, lastName:asc

@venus have you tried with /\w+:(desc|asc)/?

Looks good to me, thanks. But when I add some string after desc or asc it will still return true value:

console.log({ matched: Boolean(/\w+:(desc|asc)/.test("firstName:desca")) });

console.log({ matched: Boolean(/\w+:(desc|asc)/.test("firstName:desca")) });

You can make regex to check for end of string after desc|asc via $
