How to avoid scientific notation for large numbers in JavaScript?

Question

JavaScript converts a large INT to scientific notation when the number becomes large. How can I prevent this from happening?

Answer 1

one more possible solution:

function toFix(i){
 var str='';
 do{
   let a = i%10;
   i=Math.trunc(i/10);
   str = a+str;
 }while(i>0)
 return str;
}
