    let currencyUnit = {
        "PENNY": 0.01,
        "NICKEL": 0.05,
        "DIME": 0.1,
        "QUARTER": 0.25,

    let changeDue = cash - price
    let totalCID = Number(cid.reduce((sum, element)=> sum + element[1],0).toFixed(2))

    if (totalCID < changeDue){
        return {status: "INSUFFICIENT_FUNDS", change: []}
    } else if (totalCID === changeDue){
        return {status: "CLOSED", change: cid}
    } else {
        let changeArr = []

        for(let i = cid.length -1 ; i >= 0; i--){
            let currencyUnitName = cid[i][0]
            let currencyUnitValueTotal = cid[i][1]
            let currencyUnitValue = currencyUnit[currencyUnitName]
            let currencyUnitAmount = Number((currencyUnitValueTotal/currencyUnitValue).toFixed(0))
            let currencyUnitsToReturn = 0

            while(changeDue > currencyUnitValue && currencyUnitAmount > 0) {
                changeDue -= currencyUnitValue 
                changeDue = Number(changeDue.toFixed(2))
                currencyUnitAmount --
                currencyUnitsToReturn ++
            }

            if (currencyUnitsToReturn > 0) {
                changeArr.push([currencyUnitName, currencyUnitsToReturn * currencyUnitValue])
            }
        }
        if (changeDue > 0){
            return {status: "INSUFFICIENT_FUNDS", change : []}
        }
        return {status: "OPEN", change: changeArr}
    }

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

It would probably help to have your HTML too.

Also, can you describe in a little more detail what you think the problem is?
