DCP2 - Product in an array

// Good morning! Here's your coding interview problem for today.
// This problem was asked by Uber.
// Given an array of integers, return a new array such that each element at index i of the new array
// is the product of all the numbers in the original array except the one at i.
// For example, if our input was [1, 2, 3, 4, 5], the expected output would be
// [120, 60, 40, 30, 24]. If our input was [3, 2, 1], the expected output would be [2, 3, 6].

function productArray(arr){
    let prod = 1;
    for(let i=0; i<arr.length; i++){
        prod *= arr[i];
    }
    let newArr = []
    for(let i=0; i<arr.length; i++){
        newArr.push(prod / arr[i]);
    }
    return newArr;
}

// MAIN FUNCTION
console.log();
arr1 = [1, 2, 3, 4, 5];
console.log(productArray(arr1));
arr1 = [10, 31, 43, 24, 58];
console.log(productArray(arr1));
