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:

Bắt đầu bằng cách xem xét các định nghĩa thư viện ESNext và so sánh các JSON API của chúng với đặc tả proposal-json-parse-with-source. Sử dụng mẫu TypeScript trong issue để kiểm tra các khai báo còn thiếu, bao gồm JSON.rawJSON(), JSON.isRawJSON() và tham số ngữ cảnh của reviver, sau đó xác minh rằng target ESNext chấp nhận chúng.
