JS how to create a condition if the button is NOT pressed

Question

How to create a condition if the button is NOT pressed. Help please

Answer 1

So I'm guessing you are attaching some sort of event for clicking somewhere, and your goal is to check that the click was NOT on a specific button?

<button id="btn">Click</button>

In JavaScript:
window.addEventListener("click", function (evt) {
if (evt.target.id != "btn") {
// Code here
}
});

Answer 2

Logical operator NOT !
