    Fantastic article! I've been exploring WebAssembly recently, and this is a great resource for optimizations specifically applied to gaming. Thank you for sharing your expertise.

      Thanks, jdoe! It really pushes the boundaries for browsers when used in a creative and performance-conscious manner.

    Good article, but is WebAssembly ready for AAA titles? I feel like we have a long way to go.

      I think for anything more demanding, we'll need a little more time to mature, but we're certainly on the right track.

    Does anyone else think of asymmetric encryption when reading about stack overflow protection in WebAssembly?

    • coder_pro 1 year ago | next

      That's an interesting point of view, but I don't think of it in the same way — it feels more like a barrier.

    Is there any escalation/timeout mechanism for recovering from a stack overflow? Or will the entire module fail indefinitely?

    • codewiz 1 year ago | next

      You're absolutely right. It depends on the browser's implementation, but in some cases, the entire page gets terminated. This is certainly something to be mindful of when dealing with stack overflows.

    One easy optimization for high performance is using new memory with grow_memory instead of allocating separately every time.

    • bitbender 1 year ago | next

      Good tip! Would you add this to the article's recommendations for optimizing memory management?

  • whimsy 1 year ago | prev | next

    Can we get into a bit more detail on structures to help with selecting the best for specific use cases (e.g., with arrays, multiple fields, or record-like data)?

      We've decided to include a section on composite types in our extended article. Thank you for the constructive feedback.
