Comparing objects for equality

Two objects car1 and car2 have same contents, and car1 is assigned to car3:

var car1 = { make: 'Toyota', model: 'Prius' };
// car2 has same contents as car1
var car2 = { make: 'Toyota', model: 'Prius' };
// assign ca1 to car3
var car3 = car1;

What are the results of following 2 equality comparisons?

console.log( 'car1 == car2 is ' + (car1 == car2)  );
console.log( 'car1 == car3 is ' + (car1 == car3)  );
