Hi,
`Object` is deep in the core of JavaScript, not just Prototype.
You can add static functions to `Object` fairly safely provided you
use obscure names:
Object.myReallyObscureMethodName = function() {
// ....
};
...but as you mentioned, you will be susceptible to naming conflicts.
What you must **never** do is add to `Object.prototype`:
// DON'T DO THIS
Object.prototype.myReallyObscureMethodName = function() {
// ....
};
If you do that (the way it's shown above), then just about every
`for..in` loop in code running alongside yours will fail, because the
above adds an enumerable `myReallyObscureMethodName` property to *all
objects*:
var name;
for (name in {}) {
alert(name); // This gets reached, and alerts
"myReallyObscureMethodName"
}
...and that's just a Bad Thing(tm). (As of ECMAScript 5th edition,
it's *possible* to add non-enumerable properties to `Object.prototype`
using special syntax, but I still wouldn't do it.)
HTH,
