Wie finde ich ein bestimmtes Objekt in einem verschachtelten JavaScript-Objekt anhand der Bezeichnung?

const iterate = (obj) => {
    Object.keys(obj).forEach(key => {
        console.log(`key: ${key}, value: ${obj[key]}`)

        if (typeof obj[key] === 'object' && obj[key] !== null) {
            iterate(obj[key])
        }
    })
}
iterate(obj); // obj is the main object to be traversed

const iterate = (obj) => {
    const stack = [obj];
    while (stack?.length > 0) {
        const currentObj = stack.pop();
        Object.keys(currentObj).forEach(key => {
            console.log(`key: ${key}, value: ${currentObj[key]}`);
            if (typeof currentObj[key] === 'object' && currentObj[key] !== null) {
                stack.push(currentObj[key]);
            }
        });
    }
};

var cars = {
    label: 'Autos',
    subs: [
        {
            label: 'SUVs',
            subs: []
        },
        {
            label: 'Trucks',
            subs: [
                {
                    label: '2 Wheel Drive',
                    subs: []
                },
                {
                    label: '4 Wheel Drive',
                    subs: [
                        {
                            label: 'Ford',
                            subs: []
                        },
                        {
                            label: 'Chevrolet',
                            subs: []
                        }
                    ]
                }
            ]
        },
        {
            label: 'Sedan',
            subs: []
        }
    ]
};
