JavaScript was created thirty years ago for simple web interactions. While it still basically runs the web, applications are far more complex today than they were back then. This means there’s a lot of functionality needed in the browser that JavaScript can handle, but often at a performance cost. As someone who refreshes every few seconds while waiting for a slow app to load (yes, I know it doesn’t help, but I do it anyway), speed matters.
As a solution to this, WebAssembly (Wasm) was introduced in 2017.
