Document that Wasm code generation is disallowed

[dario-piotrowicz]

Proposed changes

In our Javascript standards section we document that eval() and new Function are not allowed for security reasons.

We should also add that wasm code generation is also disallowed.

---

Is the Javascript Standards section the best place for this information? or is there a different more proper location for this?

I'd likely follow this page from the Next.js docs: https://nextjs.org/docs/messages/edge-dynamic-code-evaluation

and mention:

• WebAssembly.compile and
• WebAssembly.instantiate
