Javascript array equal to zero but not itself

Question

I\'ve been playing around with arrays in JavaScript and cannot figure out why this happens:

Answer 1

This question is handled with the knowledge of object reference and type conversion more properly.First,in javascript, object value is stored by reference.So we can tell it is different from [] and [],because the two array correspond with two different addr in memory.Second, '==' is a not rigorous operation for both left and right, [] and 0 are both transformed to false.
