Hi i am trying to get tomorrow’s date and i am able to get it in default format  
but i need in ISO so i use this function toISOString  
This function is returning me day after tomorrow date  
var tomorrow = new Date();  
tomorrow.setDate(tomorrow.getDate() + 1);  
console.log(tomorrow.toISOString());

Any suggestion how do i fix it?

Don’t get the problem?!  
With tomorrow.setDate(tomorrow.getDate() + 1);  
you get 1549232287858 and that can be used for a new Date(). Typing on the console new Date(1549232287858) will get Date 2019-02-03T22:18:07.858Z and  
that’s the same as:  
(new Date(1549232287858)).toISOString()  
???
