How to compare two objects?

So let's say we have object "foo":

<<set $foo to { favouriteGame : "Asteroids" }>>

And we also have an object "bar":

<<set $bar to { favouriteGame : "Asteroids" }>>

Is there a function or method (like .equals()?) that I can use that compares two objects and returns true/false based on whether or not their contents are equal?
If there is and I just couldn't find it, does it compare sub-objects, too?
