Even if WASM gets some amazing feature, like super-fast DOM manipulation, it would still be used via API from JavaScript. WASM is a subset of JavaScript that mainly consists of low level operations. It's not exactly nice for writing code. It's like assembler in this respect — very fast, very efficient, but we still tend to prefer a higher level language.
How is WebAssembly a subset of JavaScript? Aren't you confusing it with asm.js?
He meant it as "wasm will be invoked by javascript" and not the other way around.
Ok but no one is talking about hand writing wasm. You write wasm with a language, such as rust, which already has great web frameworks such as yew (which replaces react) as well as leptos (which replaces solid.js). Leptos is already faster than react vue and svelte
I don’t know what you mean by WASM being a subset of javascript (maybe you mean AssemblyScript?) You can still program in higher level languages like C and have it compile into WASM as one would compile C to assembly.
