Rendering blocks using wasm(golang)

[MrRedo Gaming]

I have a blockly site https://scratch-for-discord.com and after putting 1k+ blocks the website starts lagging so i wanted to render blocks using wasm(golang)

Hello!

It is not currently possible to render blocks using wasm :/ However! We have been doing a lot of work this quarter to make performance improvements. As one example: inserting blocks into stacks is 5x faster!

So I would recommend upgrading to the next release (happening at the end of March) and seeing if that improves things for you =)

I'll also note that I'm not sure using wasm would actually improve the performance that much :/ The two most expensive parts of rendering are (1) the dom manipulations (e.g. `setAttribute` and `appendChild`) and (2) the actual rendering + painting done by the browser.

I hope that information is helpful! If you have any further questions please reply =)

The exception might be the connection database.  That's a small, fairly CPU intensive chunk of code that doesn't have any API calls.  Would love to explore whether wasm would help with that.
