toPlainObject for stripping/"normalising?" EMCAScript objects(like Date, Class) in an object

[lockieluke]

A toPlainObject function like Lodash's _.toPlainObject would be good for "normalising" JavaScript types in an object.

For example:

class ID {
    constructor(public id: string) { }
}

const response = {
	timestamp: new Date(),
	name: "Sean John Combs",
	age: 55,
	id: new ID("1234")
};

// This would transform the object into { timestamp: "2025-05-18T21:22:46.331Z", name: "Sean John Combs", age: 55, id: { id: 1234 } }
_.toPlainObject(payload);

This could be useful when you want something that can be used as a plain JSON server response

I think the idiomatic way is to JSON.parse(JSON.stringify(data)).

If performance is a concern, you could try implementing the equivalent behavior in JS and write benchmarks comparing the two solutions. If you find the perf difference is significant (order of magnitude), we can consider adding toPlainObject to Radashi. 👍
