Why using filter() in Javascript failed?

    I don't understand why this implementation fails. First I filter all zeros from the array, then add all missing zeros at the end of the array. By logging the array at the end of the method showing expected result, but submission is Wrong Answer.

    var moveZeroes = function(nums) {
        var c = nums.length;
        nums = nums.filter(n => n !== 0);
        var c1 = nums.length;
        for(var i = 0; i < c - c1; i++) {

    filter will make a copy of the array

    filter method returns a new array
    then reference of nums has been changed
