I agree. Chakra uses a pure JIT approach? I thought they interpret both in JS and Wasm?

V8 used to do this. Now they have a JS interpreter called Ignition.

It's implementation dependent. Most implementations JIT Wasm up front (I think Chakra is the only engine that interprets). So, JS loads faster because almost all engines interpret …
