JSONCT - JSON with comments and template literals

Blog Post

JSON is used all over the web, and it is used to encode so many types of data.

It is missing two critical features for many use cases though:

1. There is no native comment syntax - but JSONC fixed this by allowing JS style comments!

2. There is no support for multi-line strings, which are an extremely helpful construct for all kinds of programs.

JSONCT allows the JS template literal syntax for multiline strings as an extension of JSONC. This allows for a very natural way to write JSON documents, and is very easy to parse.

ts implementation

A JSONCT parser written in Typescript is found in src/parse.ts.

Nearly everything has been ported over from the JSONC parser in the deno std lib
