Hello guys, I'm new to TON. I wonder which is the best practice for creating and executing a smart contracts with wrapper class in typescript? In some examples like ton-onboarding-challenge or getgems, it implements Queries for building msgBody. Other examples, like ton tutorial-2 or examples in the sandbox, created wrapper classes that implement the Contract interface and put messaging methods inside of it. Which way is the latest and recommended way? I guess the latter. Is it?
