}
return arr;
}
function removeItemAll(arr, value) {
var i = 0;
while (i < arr.length) {
if (arr[i] === value) {
arr.splice(i, 1);
} else {
++i;
}
}
return arr;
}
console.log(removeItemOnce([2, 5, 9, 1, 5, 8, 5], 5));
console.log(removeItemAll([2, 5, 9, 1, 5, 8, 5], 5));
Example 3: remove item at index in array javascript
