The Cashier

Write a function named cashCounter that helps a cashier give adequate change to customers. The function should return the amount of notes and coins for the customer's change.

Example1: If the price is €3.75 and the paid amount is €50, then the client should receive €46.25 back in change.

console.log(cashCounter(3.75, 20));
// [
// { '20 Euro': 2 },
// { '5 Euro': 1 },
// { '1 Euro': 1 },
// { '0.2 Cent': 1 },
// { '0.05 Cent': 1 }
// ]

Example2: Price: €4.50, Paid amount: €20, Change: 15.50

console.log(cashCounter(4.5, 20));
// [ { '10 Euro': 1 }, { '5 Euro': 1 }, { '0.5 Cent': 1 } ]

• Include outputs for exceptions:

1. price: €4, paid amount: €3. // 'Customer should pay 1 more Euro'
2. cash box is empty or not enough coins // 'No change available'

Guidelines

1. Write a higher order function named createCashCounter.
2. This function should return an anonymous function with a cash box in its closure.

Example Cash Box:

let cashBox = [
  { 50: 10 },
  { 20: 10 },
  { 10: 10 },
  { 5: 25 },
  { 2: 25 },
  { 1: 25 },
  { 0.5: 25 },
  { 0.2: 25 },
  { 0.1: 25 },
  { 0.05: 25 },
  { 0.02: 25 },
  { 0.01: 25 },
];

3. Call the createCashCounter function and assign the returned function to a variable called cashCounter like this:

cashCounter = createCashCounter();

4. Call the cashCounter function and pass the price and paid cash as shown in the examples above.
5. Add the paid cash to cash box and deduct the change from the cashbox.
6. Call the cashCounter function with a few different price/paid cash combo and check if the cash box is updating properly.
