Moving Zeros To The End

DESCRIPTION:

Write an algorithm that takes an array and moves all of the zeros to the end, preserving the order of the other elements.

Examples

moveZeros([false,1,0,1,2,0,1,3,”a”])
// returns[false,1,1,2,1,3,”a”,0,0]

DESCRIPTION:

Write an algorithm that takes an array and moves all of the zeros to the end, preserving the order of the other elements.

Examples 

moveZeros([false,1,0,1,2,0,1,3,"a"])
// returns[false,1,1,2,1,3,"a",0,0]

My approach for solving this problem:

  • I want to loop throw the array
  • when item == 0 I need to remove it from the array then push it to the end of the array
  • return the final array

My solution: 

const moveZeros =(arr)=> {
    for (let i = arr.length - 1; i >= 0; i--) {
      if(arr[i] === 0){
        arr.splice(i, 1) && arr.push(0);
      } 
    }
  return arr
 };
