The main purpose of CloudScript is to give you the ability to build server-side logic and functionality that your client code can request execution of. You can create CloudScript functions that can only be accessed via your game, to prevent any tampering attempts from clients. For example, let’s say this game of yours gives “daily reward” to players, however, you can’t trust the client-side because they may ask for it multiple times, which is detrimental to your game. In that case, you can use CloudScript to implement a server-side validation to prevent granting the reward twice.

CloudScript has access to the full set of Server API calls, which enables your cloud code to act as a dedicated server. Usually we don’t just get the user data and return it to the clients from CloudScript, instead, oftentimes we use it in conjuction with other calls/functions to implement a more sophisticated server-side logic. I would suggest you follow through the tutorial on CloudScript to gain more insights about it.
