Override the Equivalence Comparison in Javascript

Question

Is it possible to override the equivalence comparison in Javascript?

The closest I have gotten to a solution is by defining the valueOf function and invoking valueOf

Answer 1

That is because the == operator doesn't compare only primitives, therefore doesn't call the valueOf() function. Other operators you used do work with primitives only. I'm afraid you cannot achieve such thing in Javascript. See http://www.2ality.com/2011/12/fake-operator-overloading.html for some more details.
