Algorithms - Inventory Update

JavaScript

Tell us what’s happening:

It seems that I’ve solved the challenge correctly, but tests 3 and 5 are failing. When I run the code with these test inputs for debugging, they pass but then test 6 starts to fail. After debugging test 6, it passes, but tests 3 and 5 fail again. Could you help me figure out what’s going wrong?

Your code so far

function updateInventory(arr1, arr2) {
    // return arr1;
    const updatedArray = arr1;
    const baseArray = arr1.flatMap( item => {
        return item[1]
    })
    const newInvLength = arr2.length;
    const checkInventory = (quantity, item, count) => {
        
        if(baseArray.includes(item)) {
            updatedArray.forEach(inventory => {
                if(inventory[1] === item) {
                    const oldValue = inventory[0]
                    inventory[0] = oldValue + quantity
                }
            })
        } else {
            updatedArray.push([quantity, item])
        }   
        
    }

    
    
    let count = 0;
    while(count < newInvLength) {
        checkInventory(newInv[count][0], newInv[count][1])
        count++;
    }

    if(count >= newInvLength) {
        const orderedArray = updatedArray.map((inventory) => {
             return {qtd: inventory[0], name: inventory[1]}
        }).sort((a, b) => {
            if(a.name > b.name) {
                return 1
            }
            if (a.name < b.name) {
                return -1
            }
            return 0
        }).map((inventory) => {
            return [inventory.qtd, inventory.name]
        })
        
        console.log({updatedArray, orderedArray})
        return orderedArray
    }
}

// Example inventory lists
var curInv = [
    [21, "Bowling Ball"], [2, "Dirty Sock"], [1, "Hair Pin"], [5, "Microphone"]
];

var newInv = [
      [2, "Hair Pin"], [3, "Half-Eaten Apple"], [67, "Bowling Ball"], [7, "Toothpaste"]
];

updateInventory(curInv, newInv);

Use the function parameters, not the global test variables. The function is called with the two arrays as the arguments.

newInv should be arr2
