Regex - validation for string match the following characters

Question

//^([a-z0-9]{5,})$
//Use regex.test() for boolean result:

/^([a-z0-9]{5,})$/.test('hello1');   // false
/^([a-z0-9]{5,})$/.test('hello12');   // true
/^([a-z0-9]{5,})$/.test('hello123');   // true

//you could remove the () from regex since there's no need to capture it.
