How to move all zeroes to end of array in Node.js

Answer 1

class MyArray {
    move_zeroes_to_end(arr) { 
        const size = arr.length;
      
        let j = 0;
        for (let i = 0; i < size; i++) {
            if (arr[i] > 0) {
               let tmp = arr[i];
               arr[i] = arr[j];
               arr[j] = tmp;
               j++;
            }
        }
    }
}
 
function main()
{
    var obj = new MyArray();
 
    const arr = [0, 8, 0, 0, 0, 7, 15, 0, 0, 4, 6, 9];
     
    obj.move_zeroes_to_end(arr); 
   
    console.log(arr);
}
 
main();

  
  
  
  
/*
run:
  
[8, 7, 15, 4, 6, 9, 0, 0, 0, 0, 0, 0]
