🚀 Extra

When updating a counter, it's better to pass an increase or decrease value instead of sending the new total. This helps avoid conflicts when multiple users trigger the action around the same time — otherwise, the last request might overwrite the others.

In most cases, you'll select an element and read either its innerText or a data-* attribute. I recommend using a data-* attribute for reliability, but whichever you use, always wrap the value with parseInt (or similar checks) to prevent errors if the data is tampered with or malformed.

Important: Avoid relying on syncRequest for critical or secure data. It’s meant to enhance the user experience with real-time UI updates — not to handle important state changes or data storage.
