18. Promise executor II

The code outputs:

true
true
false
true

Explanation:

• p1 is a resolved promise with a value of 1.
• p2 is a new promise resolved with p1 as the value. Since p1 is already resolved, p2 is also resolved immediately with the same value. Therefore, p1 and p2 are equal and the first console.log outputs true.
• p3 is also a resolved promise with the same value as p1. Therefore, p1 and p3 are equal and the second console.log also outputs true.
• p4 is a promise that is resolved with a new promise that is resolved with p3 as the value. Therefore, p4 is not equal to p3 and the third console.log outputs false.
• p5 is a promise that is resolved with p4. Since p4 resolves with itself as the value, p5 also resolves with the same value. Therefore, p4 and p5 are equal and the fourth console.log outputs true.
