Integers larger than 53 bits are valid JSON, but when parsed by JSON.parse they get truncated down to 53 bits and lose a few least significant digits. We have 64 bit integers coming from our backend and use https://www.npmjs.com/package/json-bigint to parse, any chance of adding an option for replace the built-in JSON.parse with a custom function, or just a boolean option for using json-bigint?
