I thought I read somewhere that the Chrome team tried typed JS, found out that there was a performance hit, and they ended the experiment? Is this a continuation of that or a new effort? Sounds interesting.

The browsers are already running anything via custom WASM interpreters, like Pyodide for Python.

With a huge performance hit and leaky abstractions.
