Missing / Incorrect Definition
JSON.rawJSON() appears to be missing. Apologies if I've missed something or if this is the wrong place to raise an issue. I searched through both PRs and issues in both this repo and https://github.com/microsoft/TypeScript-DOM-lib-generator but couldn't find any references for it.
Sample Code
// https://www.typescriptlang.org/play/?target=99#code/MYewdgzgLgBAHjAvDAUgZQPIDkB0AnAQwHd1sAKAcgAYKBKIA
const x = JSON.rawJSON('0')
Documentation Link
Per https://github.com/microsoft/TypeScript/issues/19044 it seems like TypeScript's policy is to support Stage 3+ features and proposal-json-parse-with-source is stage 3. (If I misunderstood the typescript teams policy on experimental features it would be awesome to have this documented in https://github.com/Microsoft/TypeScript/wiki/FAQ)
MDN also documents this feature here.
Additionally, it appears to have been implemented in V8 and in webkit.
Testing experimentally, it is available in node 22+ and in the latest Chromium as well:
the third parameter of the JSON.parse reviver is also missing, it seems - same proposal.
