Function parse

core/src/stdlib/pyscript/flatted.py:148–189

Parse a Flatted JSON string and reconstruct the original structure. This function takes a `value` containing a JSON string created by Flatted's stringify() and reconstructs the original Python object, including any circular references. The `*args` and `**kwargs` are passed to j

(value, *args, **kwargs)
