javascript trim()

String.trim() is quite useful in many situations. Unfortunately not all browsers have this function on String prototype (e.g. IE8): I see many people use jQuery.trim(), but isn’t it better to just use String.trim and provide a backup function if it is not implemented, like we did with Date.toISOString:

if(!String.prototype.trim) {
  String.prototype.trim = function() {
    return this.replace(/^\\s+|\\s+$/g, "");
  }
}
```EDIT: [found this solution on SO](http://stackoverflow.com/a/8522376/632117). Did we think the same?
