I'm doing this exercise where you have to calculate the number of limes needed to get the juice. It needs a switch statement inside which takes out the first element of the "limes" array, (and that works flawlessly). Until i add the condition to count down the wedges: even if in the cases is specified to subtract a determined amount, at every iteration it seems to ignore it and never meeting the needed condition to break the switch statement

here's the code

function limesToCut(wedgesNeeded, limes) {
    let limesNeeded = 0
    while(limes.length != 0 || wedgesNeeded > 0 ) {    
        switch (limes[0]) {          
            case 'small':       
                limes.shift() 
                limesNeeded += 1
                wedgesNeeded -= 6
                break;
            case 'medium': 
                limes.shift()
                limesNeeded += 1
                wedgesNeeded -= 8
                break;
            case 'large': 
                limes.shift()
                limesNeeded += 1
                wedgesNeeded -= 10
                break;
            default:
                break  
        } 
    }
    console.log(limesNeeded)
}

//test cases

console.log("case 1")
limesToCut(4, ['medium', 'small'])
console.log("case 2")
limesToCut(80,['small','large','large','medium','small','large','large',])
console.log("case 3")
limesToCut(0, ['small', 'large', 'medium'])
console.log("case 4")
limesToCut(10, [])

where did i go wrong? it seems to not be working even when i exclude the other condition from the loop
