Not so sure if this approach is Valid or Not for this Check Cash Register Project!

**Tell us what’s happening:

Howdy Y’all!! I have been working on this Check Cash Register Project, does this approach make any sense?
I was considering each calculation from given array(which I transformed to an Object called {availableUnits}) and reducing it by 1 for simplicity in each iterative calculation.

Your code so far


function checkCashRegister(price, cash, cid) {
            let billsChange;
            let currencyUnits = {
                PENNY: .01,
                NICKEL: .05,
                DIME: .1,
                QUARTER: .25,
                ONE: 1,
                FIVE: 5,
                TEN: 10,
                TWENTY: 20,
                "ONE HUNDRED": 100
            };
            billsChange = cash - price;
            let availableUnits = {};
            let funds = 0;
            let inFunds = { status: "Insufficient Funds", change: [] };
            let closed = { status: "Closed", change: [] };
            let open = { status: "Open", change: [] };
            let result;
            cid.forEach(item => {
                let key = item[0];
