+As an alternative using Cranelift as alternative to LLVM was suggested. In this case, optimization is not a primary target, but rather compilation speed, and flexibility to support target independent WASM for next-gen web applications is in focus. Also in this case bindings to external code is possible to provide interaction is possible.
