jQuery add class to element, if this class is not already there

Question

Is it any native function in jQuery which check for class in an element, and then add it if this class does not exist yet?

Use `addClass()`. Or `toggleClass` if you want to remove class if already existing. — gurvinder372, Jan 03 '18 at 08:52
This question is way too basic. Just googling "add class jquery" is the way to go, not asking SO. — Denys Séguret, Jan 03 '18 at 08:53

Just call addClass(). jQuery will do the check for you. If you check on your own, you are doubling the work, since jQuery will still run the check for you.
