Piccolo

Here is the exercise:

"3. Piccolo
Write function that:
• Records a car number for every car that enters the  parking lot
• Removes a car number when the car goes out
• Input will be array of strings in format [direction, carNumber]
Print the output with all car numbers which are in the parking lot sorted in ascending by number


Examples
Input   Output
['IN, CA2844AA',
'IN, CA1234TA',
'OUT, CA2844AA',
'IN, CA9999TT',
'IN, CA2866HI',
'OUT, CA1234TA',
'IN, CA2844AA',
'OUT, CA2866HI',
'IN, CA9876HH',
'IN, CA2822UU'] CA2822UU
CA2844AA
CA9876HH
CA9999TT
['IN, CA2844AA',
'IN, CA1234TA',
'OUT, CA2844AA',
'OUT, CA1234TA']    Parking Lot is Empty"

and here is my solution:

function piccolo(arr) {
    let cars = [];

    for (let carDetails of arr) {
       let [direction, number] = carDetails.split(', ');
       if (direction === 'IN') {
           cars.push(number);
       } else if (direction === 'OUT') {
           if (cars.includes(number)) {
            let index = cars.indexOf(number);
            cars.splice(index, 1);
           }
       }
    }

    if (cars.length > 0) {
        let sorted = cars.sort((a, b) => a.localeCompare(b));
        for (let carNum of sorted) {
            console.log(carNum);
        }
    } else {
        console.log('Parking Lot is Empty');
    }

}
