Argh, my mistake. I've got platform from browser 
window.navigator.platform which is not really true. I have a Windows 7 
64-bit and "Intel x86 or compatibles".

A, there is no differences when I type in console:

String(String.prototype.trim);
and
String.prototype.trim

because they are always converted to string. Right?
