Add method "f.defer(ms)" to functions

Add to the prototype of all functions the method defer(ms), that runs the function after ms milliseconds.

After you do it, such code should work:

          function f() {
  alert("Hello!");
}

f.defer(1000); // shows "Hello!" after 1 second
        

Function.prototype.defer = function(ms) {
  setTimeout(this, ms);
};

function f() {
  alert("Hello!");
}

f.defer(1000); // shows "Hello!" after 1 sec
