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

you can use the ES6 Object.is() function to check the property of object.

Object.prototype.equals = function(obj)
{
    if(typeof obj != "Object")
        return false;
    for(var property in this)
    {
        if(!Object.is(obj[property], this[property]))
            return false;
    }
    return true;
}
