Question

Given

    var o = {};
    var p = new Object();

    p === o; //false

    o.__proto__===p.__proto__  // true

why is this false?

please tell me the immediate reason to return false??

Answer 1

The === for objects is defined as:

11.9.6 The Strict Equality Comparison Algorithm

The comparison x === y, where x and y are values, produces true or
false. Such a comparison is performed as follows:

…

7. Return true if x and y refer to the same object. Otherwise, return
false.

In this case, although both are empty objects, they are created separately and hence do not refer to the same object.

As a side note, both constructions do the same thing; but it is common practice to use {}.
