Overview
This proposal complements the Records and Tuples Proposal. It was originally part of that proposal but split off into a separate proposal to reduce the scope of the core Records and Tuples proposal. #330
The problem being explored is ergonomic and efficient creation of a deeply immutable data structure from a JSON string.
JSON.parse(data, (key, value) => {
if (typeof value === 'object' && value !== null) {
if (Array.isArray(value)) {
return Tuple.from(value);
} else {
return Record(value);
}
}
return value;
});
Could be replaced with:
JSON.parseImmutable(data);
