// Explanation 2

  // Don't forget to take into consideration the global flag in your regexp :

  var reg = /abc/g;
  !!'abcdefghi'.match(reg); // => true
  !!'abcdefghi'.match(reg); // => true
  reg.test('abcdefghi');    // => true
  reg.test('abcdefghi');    // => false <=


  // => This is because Regexp keeps track of the lastIndex when a new match is found.
