A few months ago, there was an article at Jibbering,com with a different
version of this code:
/** @see http://jibbering.com/faq/#trimString */
if (typeof String.prototype.trim !== "function") {
String.prototype.trim = function () {
// return String(this).replace(/^\s+|\s+$/g, "");
return this.replace(/^\s+|\s+$/g, "");
};
}
I think that is more consistent with ECMA-262 5th ed., 15.5.4.20.
