Setup

var each, lettersA, lettersB, pushInto;
    each = function(array, fn) {
      var len, z;
      z = 0;
      len = array.length;
      while (z < len) {
        fn.call(null, array[z]);
        z++;
      }
    };
    lettersA = [];
    lettersB = ['a', 'b', 'c', 'd', 'e'];
    pushInto = function(val) {
      lettersA.push(val);
    };
