Why is `Object() === new Object()` equal to `false`? [duplicate]

问题

This question already has answers here:

Why are two identical objects not equal to each other? (7 answers)

Closed last year.

Why it returns false?

let a = new Object()
let b = Object()
console.log(a) // {}
console.log(b) // {}
console.log(a===b) // false

I checked a proto of a and b too and it is the same.

So what is the difference?j

回答1:

Instance of objects are not the same even:

let a = new Object();
let b = new Object();
console.log(a===b) // false
