What is the difference between call and apply?

Question

What is the difference between using call and apply to invoke a function?

var func = function() {
  alert(\'hello!\');
};
         


        

Answer 1

Call() takes comma-separated arguments, ex:

.call(scope, arg1, arg2, arg3)

and apply() takes an array of arguments, ex:

.apply(scope, [arg1, arg2, arg3])
