Given an array of n integers where n > 1, nums, return an array output such that output[i] is equal to the product of all the elements of nums except nums[i]

ProductExceptSelf.js

var productExceptSelf = function(nums) {
  //Declare a results array
  var results = [];
  //iterate through the input array
  for (var i = 0; i < nums.length; i++) {
    //Save the value in the current index in a temporary variable
    var current = nums[i];
    //get that number out of the array
    nums.splice(i,1)
    //reduce the remaining numbers and push it into results
    var product = nums.reduce(function (memo, curr, index){
      return memo * curr
    })
    results.push(product);
    //return the number to its position in the original array
    nums.splice(i, 0, current)
  }
  //return the output array
  return results;
};
