proposal-json-parse-with-source

I made this to work with Zapatos, which uses Postgres JSON extensively. Note that there is a proposal to make this possible with native JSON.parse and JSON.stringify, which would be awesome: https://github.com/tc39/proposal-json-parse-with-source

> am I misunderstanding it? The optional `context` parameter is a tc39 proposal. The feature compatibility matrix on the bottom of the MDN page is really confusing because it's showing only when `JSON.parse` was added, not whether the optional `context` parameter is supported. I've confirmed it's available in: - V8 11.4.31 - Node 20.12.0 (with `--harmony`) - Node 21.7.1 (without requiring `--harmony`) - Chrome 123.0.6312.107 But not available in: Firefox 124.0.2 (ironically) Safari 17.3.1 The original blog post linked to the proposal: https://tc39.es/proposal-json-parse-with-source/ https://github.com/tc39/proposal-json-parse-with-source This issue links to the various browser engine tracking bugs: https://github.com/tc39/proposal-json-parse-with-source/issu... Which are: • Chrome/V8: https://bugs.chromium.org/p/v8/issues/d

JS is likely to get a hook to be able to handle serialization/deserialization of such values without swapping out the entire implementation[1]. Native support for these types, without additional code or configuration, would likely break the Internet badly, so is unlikely to happen unfortunately. 1: https://github.com/tc39/proposal-json-parse-with-source
