IE and named function expressions

Show all headers | View raw

I'm sure this has been discussed before but I can't find it. The
following code:

  var foo;
  (function() {
    foo = function foo(){};
  }());

  alert(typeof foo);

shows "function" in most browsers but "undefined" in IE. It appears
that IE is creating a local variable foo inside the anonymous function
as a consequence of the named function expression. So the function is
assigned to a local variable and goes out of scope for the alert. But
in non-IE browsers, foo resolves to the global foo and is in scope for
the alert.

Is this consistent with ECMA-262 or not? I'm simply not up to wading
through the spec in sufficient detail to answer the question myself.
