Problem with Cash register Problem

JavaScript
1

Tell us what’s happening:
The way this problem is designed, I guess there’s some problem with the 5th test. can anyone help me with what I should do to return all the denominations
only when the status is closed.
Thanks in advance!

Your code so far


function checkCashRegister(price, cash, cid) {
  let denom = [
  { name: "ONE HUNDRED", val: 100.0 },
  { name: "TWENTY", val: 20.0 },
  { name: "TEN", val: 10.0 },
  { name: "FIVE", val: 5.0 },
  { name: "ONE", val: 1.0 },
  { name: "QUARTER", val: 0.25 },
  { name: "DIME", val: 0.1 },
  { name: "NICKEL", val: 0.05 },
  { name: "PENNY", val: 0.01 }
];
  let change = cash-price;
  let changeArr=[],f=0,ctr=0;
  let totalCash =0; 
  cid.map(item=>{
    totalCash+=item[1];
    denom.map(den=>{
      if(den.name===item[0]){
        den.fund = item[1]
      }
    })
  });
  if(totalCash<change)
    return {status: "INSUFFICIENT_FUNDS", change: []};
     denom = denom.map((den)=>{
      ctr=0;  f=0;
      while(change>=den.val && den.fund>=den.val){
        change-=den.val;
        den.fund-=den.val;
        change = Math.round(change*100)/100;
        den.fund = Math.round(den.fund*100)/100;
        ctr++
        f=1;
      }

      if(f===1){
        changeArr.push([den.name, ctr*den.val])
       
      }
   
      return den;
      
    })
    totalCash=0;
    denom.map(den=>{
      totalCash+=den.fund;
    })
  if(change!==0){
    return {status: "INSUFFICIENT_FUNDS", change: []};
  }
  console.log(totalCash, changeArr)  
  if(totalCash==0)
  return {status:'CLOSED', change:changeArr};

  return {status:'OPEN', change:changeArr};
}

checkCashRegister(19.5, 20, [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]])

i dont think this part looks good, for calculating the total cash, use

var totalCash = cid.reduce(accumulator, elem)=>accumulator+elem[1])

also, for the change variable use var keword, for variables that you’d need to access within the whole function (in multiple loops and if statements) it’s better to use var keyword

3

where are the curly braces for the if?
if you want to write it without them don’t have a new line

4

also, when you’re using map remember that it returns a new array, it doesnt change the array it acts on, when you want to change an array with map use

array_name = array_name.map(actions)
