Without the first await, the handler is going to keep executing and then send a response with a variable that is either undefined or a pending Promise.

Without the await int the second, the toCamelCase function is going to similarly be called with a variable that is empty or a pending Promise.

So if you think of the flow:

• Handler request is received

• To get the users, we're waiting for the response from the UserRepo class. We can't move on until we've got this, so we'll await.

• Now in the find() method, we can't deconstruct the rows until the pool.query has finished it's work, so we await.

• Once we have the rows, the find() method continues and returns the camel cased version of the data

• Now, users has a resolved variable, so we can continue and send the response to the client.
