Move Zeroes

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

Note:
You must do this in-place without making a copy of the array.
Minimize the total number of operations.

/**
 * @param {number[]} nums
 * @return {void} Do not return anything, modify nums in-place instead.

var moveZeroes=function(nums){
    var count=0;
    for(var i=0;i<nums.length;i++){
        if(nums[i]!==0){
            nums[count]=nums[i];
            count++;
        }
    }

    for(;count<nums.length;count++){
        nums[count]=0;
    }
};
