IMHO the advantage of zig isn’t performance but generating a minimal library that exports C headers, making it simple to integrate in any language. My use case is a custom document editor in zig, with a “bring your own renderer” approach”. It integrates in a C# desktop app, as a base for something like a modern RichEditBox (just in spirit - not RTF based, with way more advanced features).
I want the editor to be usable in other GUI stacks, a C-compatible library is the only approach that makes sense here
How it will work if you don't know target platforms in advance? Will you compile zig module for every possible native target you know? Is sorce code public or only compiled library? WASM is universal solution, compile once run it everywhere. There is a reson why Microsoft Flight Simultor choosed WASM modules for plugin system.
