# How to sort the array in correct order to match all test cases

Tell us what’s happening:
i have tried both `chngArr[].sort((a,b)=> a[1] > b[1])` and `chngArr[].sort((a,b)=> a[1] < b[1])`. but both cases are sorting `chngArr` into desired one. it’s giving the same output in both cases.

function checkCashRegister(price, cash, cid) {
// Here is your change, ma'am.
let currarr = ['Penny','Nickel','Dime','Quarter','Dollar','Five Dollars','Ten Dollars','Twenty Dollars','One-hundred Dollars'];
let currVal =[0.01,0.05,0.1,0.25,1,5,10,20,100];
let change = cash - price; // change to provide
let change1 = change;
let chngArr = []; //array to store change values
let paidCash = 0;
let totalCash = 0;
for(let i = cid.length-1;i>=0; i--){
let e = cid[i];
totalCash += e[1];
if(currVal[i] > change && e[1] > 0){
continue;
}
else {
if(paidCash < change1 && change > 0 ){
let t = Math.floor(change/currVal[i]);
let currchg = t*currVal[i] < e[1] ? t*currVal[i] : e[1];
chngArr.push([e[0], currchg]);
change -= currchg;
paidCash += currchg;
paidCash = parseFloat(paidCash.toFixed(2)); // convert to 2 decimal places
change = parseFloat(change.toFixed(2));
}
}
// console.log(paidCash, change);
}
chngArr.sort((a,b)=> a[1] < b[1]);
// console.log(chngArr);
console.log(change1,paidCash, totalCash);
if(change1 > paidCash ){
return {status: "INSUFFICIENT_FUNDS", change: []}
}
else if(paidCash === change1 && totalCash > change1){
return {status: "OPEN", change: chngArr};
}
else if(totalCash === change1){
return {status: "CLOSED", change: chngArr};
}
else{
return { status:'OPEN', change: chngArr};

}
// console.log(currarr,currVal);
}

// Example cash-in-drawer array:
// [["PENNY", 1.01],
// ["NICKEL", 2.05],
// ["DIME", 3.1],
// ["QUARTER", 4.25],
// ["ONE", 90],
// ["FIVE", 55]
// ["TEN", 20],
// ["TWENTY", 60],
// ["ONE HUNDRED", 100]]
let results = checkCashRegister(19.5, 20, [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]]);
console.log(results.change, results.status);

Check out the documentation for Array.prototype.sort. Your comparator function needs to return a number value, not a boolean. Try `a[1] - b[1]`.
