How to segregate even and odd numbers of an array (even on left and odd on right) in JavaScript

Answer 1

function segregateElement(arr) {
	const size = arr.length;
 
   	let j = 0;
 
    for (let i = 0; i < size; i++) {
         if (arr[i] % 2 == 0) {
             [arr[j], arr[i]] = [arr[i], arr[j]];
             j++;
         }
    }
 }
 
const arr = [1, 3, 4, 5, 7, 10, 13, 6, 9, 8];
 
segregateElement(arr);
 
console.log(arr.toString());
   
   
 
   
/*

"4,10,6,8,7,3,13,1,9,5"
   
*/
