> The replacement for those technologies is arguably javascript. WASM is more focused on performance by providing less abstractions and an instruction set closer to assembly (hence the name). That is nonsense. WASM and JS have the exact same performance boundaries in a browser because the same VM runs them. However, WASM allows you to use languages where it's easier to stay on a "fast-path".
