No, you just have to make sure that the variable does not exist already. window.name does exist already, and your assignment collides with that. name = actually calls a setter, which casts the array to a string, and therefore you get the second strings character with name[1].

  window.name = ["a", "b"];
  console.log(window.name); // "a,b"
