Guess the Output with explanation ❓

456 is output,

— Object keys are automatically converted into strings. We are trying to set an object as a key to object a, with the value of 123.

— However, when we stringify an object, it becomes "[object Object]".

1/3

— So what we are saying here, is that a["[object Object]"] = 123. Then, we can try to do the same again. c is another object that we are implicitly stringifying. So then, a["[object Object]"] = 456.
