JavaScript performance difference with time(int) declaration?

Question

What it is the difference in having:

setInterval(function(){

},5000);

and:

setInterval(function(){

},5E3);

I know that 5E3 is like saying 5*1000 but is there is any benefits one from another way to declare times?

Answer 1

No, there's no difference, as both literals are parsed into the same primitive number.
