I noticed that document.getElementById is a function in Firefox and Chrome, while typeof considers it an object in IE8 (at least).
Anyone has an idea why?

IE8 (attempts to) implement ECMAScript 3 where the
typeofoperator result is implementation defined for host objects regardless if the object implements [[call]]. In ES5, callable host objects must return"function".See the table in ECMAScript 3
Compare to ECMAScript 5.1 http://www.ecma-international.org/ecma-262/5.1/#sec-11.4.3
