How to move all zeroes to end of array in TypeScript

Answer 1

function move_zeroes_to_end(arr: number[]) { 
    const size: number = arr.length;
   
    let j: number = 0;
    for (let i = 0; i < size; i++) {
        if (arr[i] > 0) {
           let tmp = arr[i];
           arr[i] = arr[j];
           arr[j] = tmp;
           j++;
        }
    }
} 
  
  
const arr = [0, 8, 0, 0, 0, 7, 15, 0, 0, 4, 6, 9];
 
 
move_zeroes_to_end(arr); 
   
console.log(arr);
  
  
  
  
/*
run:
  
[8, 7, 15, 4, 6, 9, 0, 0, 0, 0, 0, 0] 
  
*/
