Create repeating function. Takes arguments from first call and repeat on each call there after.

gistfile1.js

function repeater(fn) {
  var args = false;
  return function() {
    if(args === false) args = arguments;
    return fn.apply(this, args);
  }
};


function add(a, b) {
  return a + b;
};

var r = repeater(add);
console.log(r(1,2));
console.log(r(2,2));
