[Gambas-user] Does anyone have any thoughts on webassembly

[Jussi Lahtinen]

You are right. Gambas JIT does not make standalone C code, it is heavily
dependent on the interpreter. I don't think there is an easy way to compile
even a skeleton version of Gambas into WebAssembly. WebAssembly makes
restrictions on what the code can do and for example not all libraries are
available. IE you cannot even compile just an arbitrary C program into
WebAssembly, you need to design it to be used so.
