Are all attributes of an object evaluated at the same time in Nodejs?

Let’s take this code:

{ a: Date.now(), b: Date.now() }

It returns: { a: 1664294035466, b: 1664294035466 }

Can I be sure that the keys a and b will always have the same value?

>Solution :

No, you cannot. Date.now returns the current time at the exact moment it is called. This code will call it twice, and it’s possible (with luck) that the timer ticks over to the next millisecond in between the calls.
