Why, unlike Python for example, the following post(item) code outputs the index of each item in the list, not their value.

function test() {
  var list = ['a','b','c','d'];
  for (item in list) {
    post(item);
  }
}

Although that's not a great practice. See:

function test() {
	var list = ['f','b','c','d'];
	for (item in list) {
		post(list[item]);
	}
}

I know how to get the right output, I'm just curious why the implementation is different from python.

Thanks for the link!
