Tell us what’s happening:

all other tests are completed but only this is not getting fulfilled. checkCashRegister(3.26, 100, [[“PENNY”, 1.01], [“NICKEL”, 2.05], [“DIME”, 3.1], [“QUARTER”, 4.25], [“ONE”, 90], [“FIVE”, 55], [“TEN”, 20], [“TWENTY”, 60], [“ONE HUNDRED”, 100]]) should return {status: “OPEN”, change: [[“TWENTY”, 60], [“TEN”, 20], [“FIVE”, 15], [“ONE”, 1], [“QUARTER”, 0.5], [“DIME”, 0.2], [“PENNY”, 0.04]]}.

Your code so far

function checkCashRegister(price, cash, cid) {
  
  const currencyMap = {
    PENNY: 0.01,
    NICKEL: 0.05,
    DIME: 0.1,
    QUARTER: 0.25,
    ONE: 1,
    FIVE: 5,
    TEN: 10,
    TWENTY: 20,
    "ONE HUNDRED": 100
  };

  let changeDue = cash - price;
  
  let drawerTotal = 0;
  for (let i = 0; i < cid.length; i++) {
    drawerTotal += cid[i][1];
  }

  if (changeDue > drawerTotal) {
    return { status: "INSUFFICIENT_FUNDS", change: [] };
  }

  if (changeDue === drawerTotal) {
    return { status: "CLOSED", change: cid };
  }

  let changeToReturn = [];
  for (let i = cid.length - 1; i >= 0; i--) {
    let currency = cid[i][0];
    let currencyValue = currencyMap[currency];
    let currencyAmount = cid[i][1];
    let currencyToReturn = 0;

    while (changeDue >= currencyValue && currencyAmount > 0) {
      currencyToReturn += currencyValue;
      changeDue -= currencyValue;
      currencyAmount -= currencyValue;
    }

    if (currencyToReturn > 0) {
      changeToReturn.push([currency, currencyToReturn]);
    }
  }

  
  if (changeDue > 0) {
    return { status: "INSUFFICIENT_FUNDS", change: [] };
  }

  return { status: "OPEN", change: changeToReturn };
}
