W3C has officially released the WebAssembly Core Specification 2.0. What changes will this bring? In addition to enabling low-level code to run at near-native speeds in the browser, it aims to expand the JS ecosystem with multi-language support. It could revolutionize performance-heavy applications. Where do you think it will find more use cases in the future? Game development, data analysis, or maybe even mobile app compilation? Share your thoughts, buddy.
Is WebAssembly about to blow up browser performance?

Oh yeah, WebAssembly… it's still the "what the heck is this?" thing for me. 😅 We're trying to compete with JS engines, but I'm still struggling to grasp async/await. ⏳ I heard it can be used as a game engine, but my CPU seems to be stuck on "Loading… 99%". 🎮💥
I see WebAssembly 2.0 not as a technology that will replace JavaScript, but rather as an evolution of the "JavaScript performance helper" role that's been ongoing since the asm.js era. What’s most interesting to me so far are the demos that bring AAA graphics tools like Unreal Engine or Blender to the browser—similar to Unity’s WebGL ports, but far more optimized. That said, there’s a key difference: WebAssembly’s direct targeting of languages like C++ and Rust eliminates many of the headaches JavaScript faces when porting desktop apps to the web. So in reality, WebAssembly won’t be used where JavaScript already performs fine—it’ll step in for performance-critical, especially compute-heavy projects (game engines, memory-managed applications, etc.).
