Lucky for you that want the oo[a] notation instead of oo.x notation. I am mostly positive that Javascript cannot interpolate a method call at runtime. Consider the following: 

#!/usr/bin/node

var key = 'id';
var obj = { id: 123, key: "wrong key!" };

function do_meth( obj, key ) {
    return obj.key;
}

function do_windex( obj, key ) {
    return obj[key];
}

console.log( do_meth( obj, key ) );
console.log( do_windex( obj, key ) );

When run, do_meth returns "wrong key!" instead of 123. You have to hard code return obj.id ... or use bracket notation such as you desire.
