findProduct.js

function findProduct(arr) {
  	// First find the total product of all indeces
    let totalProduct = arr[0];
    for (let i = 1; i < arr.length; i++) {
        totalProduct *= arr[i];
    }
  
  	// Then, return a new array where each index is the
  	// product of all numbers, except for the current value of that index
	// i.e. newArr[0] = arr[1] * arr[2] * arr[3]... arr[length-1];
  	// i.e. newArr[1] = arr[0] * arr[2] * arr[3]... arr[length-1];
  	// We can do this by just dividing by the number at arr[i] to get the
    // remaining product
    return arr.map(num => totalProduct / num);
}

i love the reasoning behind this. great job
