Hi,
Eventhough it seems that my out is correct, I can’t get the test pass. Can someone tell me what is happening here?
let currency={
"PENNY":0.01,
"NICKEL":0.05,
"DIME":0.1,
"QUARTER":0.25,
"DOLLAR":1,
"ONE":1,
"FIVE": 5,
"TEN":10,
"TWENTY":20,
"ONE HUNDRED":100
};
//Function which return the total value in the CID.
function totalInCashRegister(cid){
return Math.round(cid.reduce((acc,x)=>{return acc+x[1]},0)*100)/100;
}
//function that giving a cahnge valie and an element of a CID return how ,uch from that notebank you can give to the customer and the left change
function emptyDrawer(change,array){
let valueNote=currency[array[0]];
let numberCoins=array[1]/valueNote;
let returnChange=0;
while(numberCoins>0 && change>=valueNote){
change=Math.round((change-valueNote)*100)/100;
numberCoins=Math.round((numberCoins-1)*100)/100;
returnChange=returnChange+valueNote;
}
if(returnChange>0){
return [[[array[0],Math.round(returnChange*100)/100]],change];
}
else{
return [[null],change ]
}
}
//function taking the whole CID and return the cash and the left change.
function returnCashToCustomer(change,cid){
return cid.reverse().reduce((acc,x)=>{
let emptying=emptyDrawer(acc[1],x);
if(emptying[1]!=acc[1]){
acc[1]=emptying[1];
acc[0].push([emptying[0]]);
}
return acc;
},[[],change])
}

var change=cash-price;
var output = { status: null, change: [] };
// Handle exact change
if (totalInCashRegister(cid) === change) {
output.status = 'CLOSED';
output.change = cid;
return output;
}
// Handle insufficient funds
if (totalInCashRegister(cid) < change) {
