Question about fast-deep-equal HOT 2 CLOSED

Custom toString method is supposed to be used to generate string representation of the object - the idea here is that if it was overridden in some useful way as Mozilla recommends (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/toString) then it would generate equal representation for equal objects, and unequal for unequal. Of course it can be defined in not as useful way, as in your example (in the same way as custom equality operator in some other languages can be defined to do what you want)...

Thank you for the answer. However, I think it probably should be added to the documentation to prevent possible confusion. Of course, nobody would return a constant in toString(), but I saw toString() implementations that ignore part of of object attributes (probably for historical reason). It may lead to rather bad bugs.
