What is the difference between call and apply?

What is the difference between using Function.prototype.apply() and Function.prototype.call() to invoke a function? const func = function() { alert("Hello world!"); }; func.apply() vs. func.call() Are there performance differences between the two aforementioned methods? When is it best to use call over apply and vice versa?
