How to convert an object containing functions to JSON and back?

Question

JavaScript

Hello! There is an object in which there are fields containing various data, including nested ones, and containing functions.
JSON.stringify() cannot convert a function to a string.
Question - how can I convert the entire object to JSON, and then parse it back to the original object?
The .toSource() method can do this, but how do you return it back to the original function? eval()? Not suitable - because it is inconvenient - you need to completely restore the original object from the string.
