What is the best way to compare Objects in JavaScript?

Example:

var user1 = {name : "nerd", org: "dev"};
var user2 = {name : "nerd", org: "dev"};
var eq = user1 == user2;
alert(eq); // gives false

I know that "Two objects are equal if they refer to the exact same Object", but is there a way to check it another way??

Using this way works for me.....but is it the only possibility?

var eq = Object.toJSON(user1) == Object.toJSON(user2);
alert(eq); // gives true
