--parser typescript

Input:

(await (await fetch()).json()).foo

Output:

await(await fetch()).json().foo;

Expected output:

(await (await fetch()).json()).foo

Why?

The parentheses are necessary to await the .json() response.

For comparison, it works fine with the babel parser. (Is the typescript parser deprecated? I don't think so.)

I found a very old similar bug. Also an active area of discussion.
