The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
return a * b;
}
var specifiedElement = document.getElementById(%27a%27);
//I%27m using "click" but it works with any event
document.addEventListener(%27click%27, function(event) {
var isClickInside = specifiedElement.contains(event.target);
if (!isClickInside) {
//the click was outside the specifiedElement, do something
}
});
