Moving Zeros To The End

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

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

Solution

var moveZeros = function (arr) {
  return arr.filter(a=>a!==0).concat(arr.filter(a=>a===0))
}
