Please verify that my logic makes sense, thanks you

```
function checkCashRegister(price, cash, cid) {
var changeOwed = cash - price; /*returns the amount given minus the amount it costs*/
var change = []; /*Sets the change to empty array to display an amount when due change is calculated*/
var totalCid = 0; /*Initializes the total cash in drawer*/
for (var i = 0; i < cid.length; i++) {
totalCid += cid[i][1]; /*Loops through the total cash in the drawer and then adds it all together to give totalCid a new value of the actual amount in drawer */
}
if (totalCid < changeOwed) { /*if the total cash in drawer is less than change owed to person*/
return {status: "INSUFFICIENT_FUNDS", change: []}; // if the total cash in drawer is less than the change owed it returns insufficient funds to give
}
// check if cash in drawer is equal to change due
if (totalCid === changeOwed) { // if the the total cash in drawer is exactly the change of amount owed to person
return {status: "CLOSED", change: cid}; // the calculation completes and gives the cash in drawer with the amount displayed
}
// the units that are used/declared when calculating change to be given

var nameOfCurrency = currencyValue[i][0]; // Then gives the currency names a value by accessing it through bracket notation using the first array at 0 index
var valueOfCurrency = currencyValue[i][1]; // Gives the value of currency names a value of the amount it is equal to
if (changeOwed >= valueOfCurrency) { // if the change owed to persons is more than and equal to the amount of the currency
