Which browsers do not support the get and set methods for object prototypes? I believe this is a feature of ES5, an I know it works in Chrome, but I am wondering if it is safe to use for ajax apps. Here's an example:

var foo = function () {};
foo.prototype = {
    get name () {
        return this._name;
    },
    set name (n) {
        this._name = n || "bar";
    }
};

Here's a patibility table for you.

http://kangax.github./es5-pat-table/

See the Getter in property initializer and Setter in property initializer rows.

According to the table:

• Firefox 4
• Safari 5
• Chrome 7-11

Other browsers (including IE9) are not given a Yes or No, so perhaps they're untested. I'm pretty sure IE9 supports it.
