# The JavaScript Algorithms and Data Structures Projects: Cash Register

The test returns are all showing no pass even when console.log shows accurate return results. The first should return by default of the code and the results for the last test should return.

``````// Create an array of objects which hold the denominations and their values

const DENOMINATIONS = {//unit of currency.

"PENNY": 1,//index[0]

"NICKEL": 5,

"DIME": 10,

"QUARTER": 25,

"ONE": 100,

"FIVE": 500,

"TEN": 1000,

"TWENTY": 2000,

"ONE HUNDRED": 10000//index[8]

}

function checkCashregister(price, cash, cid) {

let changeSum = Math.round(cash * 100) - Math.round(price * 100);

let changeSumCheck = changeSum;

let change = [];//empty array

let status = '';//empty string

let cidSum = 0;

//will iterate from 'ONE HUNDRED' to 'PENNY'.

let filteredCid = cid.filter(item => item[1] !==0).reverse();//also will filter through denomination to verify enough change or return 'insufficient funds'.

filteredCid.forEach(item => {

let denom = item[0];//key_item(denomination).

let denomSum = item[1] * 100;//key_item value

cidSum += denomSum;

let amount = 0;

while (changeSum >= DENOMINATIONS[denom] && denomSum > 0){

//will iterate to add to change given to cust

amount += DENOMINATIONS[denom];

changeSum -= DENOMINATIONS[denom];//while decreasing denom amount from cid

denomSum -= DENOMINATIONS[denom];//while decreasing value amount from cid

}

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

It might be something really tiny like the letter case or missing an array or nested array.
