Is there a way to test circular reference in JavaScript?

Question

I\'m making a game, and I\'ve come across a problem... When I try to save, JSON fails and reports that circular reference is being made somewhere. I don\'t think it actually

Answer 1

I was thinking about what you're trying to accomplish based off the initial code from your other question. Why not do something like this.

Player = function()
{
    this.UnitTypeXpower = 2
    this.UnitTypeYpower = 7

}

UnitTypeXAdd = function(owner)
{
    owner.UnitTypeXpower++;   
}

That way you don't have to use a circular reference and it accomplishes the same thing.
