I learned for an upcoming exam and found something strange.
Here is the prompt for the question:
They have a fashion catalog, a collection of articles from various high-fashion designers. Every designer has a number of shoes. Every shoe has a name and a price.
It looks like this:
var currentInventory = (
{
name: 'Brunello Cucinelli',
shoes: (
{name: 'tasselled black low-top lace-up', price: 1000},
{name: 'tasselled green low-top lace-up', price: 1100},
{name: 'plain beige suede moccasin', price: 950},
{name: 'plain olive suede moccasin', price: 1050}
)
},
{
name: 'Gucci',
shoes: (
{name: 'red leather laced sneakers', price: 800},
{name: 'black leather laced sneakers', price: 900}
)
}
);
Your function should return the average cost of all shoes per designer in this format:
var expected = {
'designers': (
{
'name': 'Brunello Cucinelli',
'averagePrice': 1025
},
{
'name': 'Gucci',
'averagePrice': 850
}
)
};
I've written code and it behaves differently, whether I'm running it on Repl.it or the Hack Reactor Lab site. Here is my code:
function calculateAveragePricePerDesigner(inventory) {
var result = {designers: ()};
var parsedDesignerAverageCost = ();
for (i = 0; i < inventory.length; i++) {
parsedDesignerAverageCost.push(parseAverageCostPerDesigner(inventory(i)));
console.log(parsedDesignerAverageCost);
}
result.designers = parsedDesignerAverageCost;
return result;
}
function parseAverageCostPerDesigner(currentDesigner) {
var currentShoes = currentDesigner.shoes;
var result = {
name: currentDesigner.name,
averagePrice: 0
};
var cummulativeCost = 0;
var numOfShoes = currentShoes.length;
for (i = 0; i < numOfShoes; i++) {
cummulativeCost += currentDesigner.shoes(i).price;
}
var average = cummulativeCost / numOfShoes;
result.averagePrice = average;
return result;
}
Can someone explain if my code is correct or not and possibly why the inconsistency occurs? My code is compiled on Repl.it but not executed in a way I can not explain, and it is not compiled on the Hack Reactor site.

Many thanks
