Code

const v = await (1);

Expected behavior:
No error thrown. (If renaming this file to .js extension, it would be accepted by runtimes that enables top-level await e.g. Deno, indicating this is accepted by engines like V8)

Actual behavior:

error TS2304: Cannot find name 'await'.

    Sorry, I thought 3.7 turns on top-level await support. Turns out Deno turns off top-level await warnings ourselves and TLA support for TS is not fully completed yet

    As a reference, #25988 tracks adding top level await. Currently planed for 3.8.
