In an Array move zero element to bottom of array

Given an array modify array in such a way that all

zero element are at end non zero element at front

Code

var arr=[5,8,-45,0,6,0,10,-1,67];

console.log("Original Array",arr)

let nonZero = arr.filter((item)=>{

 return item !=0

})

let zero = arr.filter((item)=>{

 return item ==0

})

arr = [...nonZero,...zero]

console.log("Final Output:",arr)

Output:

    Original Array [

    5,  8, -45,  0, 6,

    0, 10,  -1, 67

    ]

    Final Output: [

    5,  8, -45, 6, 10,

    -1, 67,   0, 0

    ]

Another way

var arr = [5, 8, -45, 0, 6, 0, 10, -1, 67];

let j = 0;

for (let i = 0; i < arr.length; i++) {

    if (arr[i] !== 0) {

        [arr[i], arr[j]] = [arr[j], arr[i]];

        j++;

    }

}

console.log("Final Output:", arr)
