From You Can't to You Can: The Welcoming Nature of JavaScript
summary
Walks through concrete examples: apps that display queries of 16 million rows, using TypeScript that ultimately runs as JavaScript; live demo compiles a Rust library with wasm-pack into Rust→Wasm, publishes it to npm, imports the module and calls an exported say_hello function that triggers a browser alert (demo succeeds). Covers recent API additions like array.flat/flatMap, explains backward compatibility and community-driven TC39 process, and argues WebAssembly removes previous performance limits so JS can power larger, higher-performance systems.
