By "Wasm JIT API in JavaScript" I mean a native way for the browser to support the JIT use-case.

Generating entire modules works, but it has a number of issues.

For example, you need to carefully decide how big your modules are going to be:

- Too small, and you end up compiling many many modules, which eventually crashes the browser if you don't dispose of the old ones

- Too big (many functions batched together), and you have too much latency before your code is available to run

Being able to compile a single function to add to an existing module (or something like that) would help a lot.
