So I have this problem with strings and switch-case, and I'll try to keep it as simple as possible.

Here event.keyCode has the value "65", and is the result of a keydown event of 'a' (using JQuery).

if (event.keyCode == "65") {
   alert("hmmmm");
}

That works, but:

switch (event.keyCode) {
   case '65':
      alert("Yay!");
      break;
}

That doesn't. However this will work:

switch ('65') {
   case '65':
      alert("Yay!");
      break;
}

And if I do this:

var t = '65';
switch (t) {
   case '65':
      alert("Yay!");
      break;
}

It works. And then I tried this:

var t = event.keyCode;
switch (t) {
   case '65':
      alert("Yay!");
      break;
}

But it fails!

So why does it match in the if-block at the beginning, but not for the switch-case?
