Check whether a string matches a regex in JS

Question

I want to use JavaScript (can be with jQuery) to do some client-side validation to check whether a string matches the regex:

^([a-z0-9]{5,})$

Answer 1

const regExpStr = "^([a-z0-9]{5,})$"
const result = new RegExp(regExpStr, 'g').test("Your string") // here I have used 'g' which means global search
console.log(result) // true if it matched, false if it doesn't
