Translate Requests Between Stores with Different Selling Units

This JavaScript code provides a solution for translating requests between two stores, storeABC and storeDEF, that sell the same item ABC KOPI MILK, but with different units of measurement and amounts.

The stores are defined as objects with the properties name and items. The items property is an array of objects, where each object represents a different item and contains the properties name, unit, and amount.

1const storeABC = {
2  name: 'ABC Shop',
3  items: [
4    {
5      name: 'ABC KOPI MILK',
6      unit: 'Box',
7      amount: 12,
8    },
9  ],
10};
11
12const storeDEF = {
13  name: 'DEF Shop',
14  items: [
15    {
16      name: 'ABC KOPI MILK',
17      unit: 'Jointly',
18      amount: 1,
19    },
20  ],
21};

In this example, storeABC has one item ABC KOPI MILK that is sold in the unit of Jointly with an amount of 12 Jointly per Box. On the other hand, storeDEF has the same item ABC KOPI MILK that is sold in the unit of Jointly with an amount of 1 Jointly per Jointly.

The function convertUnits takes in two stores, fromStore and toStore, as well as the itemName of the item to be transferred, and returns the conversion factor necessary to convert the units from one store to the other.

1function convertUnits(fromStore, toStore, itemName) {
2  let fromItem;
3  let toItem;
4
5  for (const item of fromStore.items) {
6    if (item.name === itemName) {
7      fromItem = item;
8      break;
9    }
10  }
11
12  for (const item of toStore.items) {
13    if (item.name === itemName) {
14      toItem = item;
15      break;
16    }
17  }
18
19  if (!fromItem || !toItem) {
20    console.error(`Item not found in either store: ${itemName}`);
21    return;
22  }
23
24  if (fromItem.unit === toItem.unit) {
25    console.error(
26      `The units for the item are the same in both stores: ${fromItem.unit}`
27    );
28    return;
29  }
30
31  let conversionFactor = toItem.amount / fromItem.amount;
32
33  return Math.ceil(conversionFactor);
34}

Finding the items in both stores

First, the function uses a for...of loop to find the item in both stores, and saves the item objects as the variables fromItem and toItem. If either of these items is not found in the respective store, the function returns an error message using console.error.

Checking if units are the same

Next, the function checks if the units for the item are the same in both stores. If so, it returns another error message using console.error.

Calculating the conversion factor

Finally, the function calculates the conversion factor by dividing the amount of toItem by the amount of fromItem. The conversion factor is then returned from the function and saved in the variable conversionFactor. The conversion factor represents the number of units of the toStore that can be obtained for each unit of the fromStore.

Logging the conversion factor

Finally, the code logs the conversion factor using console.log. The returned value will represent the number of units of toStore that can be obtained for each unit of fromStore. In this example, the returned value would be 1 since 1 Jointly is equal to 12 Renteng.

Note that the code uses Math.ceil to round the conversion factor up to the nearest whole number. This ensures that the returned conversion factor is an integer, even if the calculation results in a fractional value.
