body: <p>What languages can be compiled to WebAssembly (Wasm)?</p>
  
  <p>I believe right now C, C++, and Rust (experimental) can be compiled to WebAssembly, with the llvm compiler backend, with languages like Java, Swift, and C# not currently being supported, but being possible candidates for future development.</p>
  
  <p>I don't believe JavaScript can be compiled to Wasm.
