Move more parts of the tutorial to rust about wasm_game_of_life HOT 4 CLOSED

Here is an example how it may look like

If you like an idea, I'll submit a pr

I think it is valuable to show off how to have JS and Rust/Wasm interact with each other. While the whole game of life could definitely be implemented in Rust/Wasm without any hand-written JS, it wouldn't help people learn the skills necessary for incrementally replacing some JS module with Rust and having them work well with each other.

Hi all! I am new to the rust community. I tried to reimplement all javascript in pure rust, including click handling and play/pause. Below is my code. I can't create a pull request though (because cannot request a new branch).

I can also share my experience. I think it is somewhat cleaner and actually produces less hassle to implement whole app in rust, because I don't have to concern too much about the rust-javascript interface and the efficiency.

On the other hand, handling javascript objects in rust is a pain in the butt, especially dealing with HTML5 APIs and event listeners.

I think we may consider extending the tutorial to discuss this matter further, or dedicate a new tutorial about implementing HTML5 apps in pure rust.
