<div dir="ltr">Hi Michael,<div><br></div><div>I am afraid I cannot give you "definitive" answers for much of your questions.

- I had to pass both a "gameState" and a "source gameState" parameter to the "render" function (for the same game state). Is there a way around that?<br></blockquote><div>Yes.

- I minimized the use of mutable data. So when the game state changes much of the page gets updated. This should probably be done in a more fine-grained way in reality.<br></blockquote><div>As long there is no performance problem, I think your implementation is fine.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
