Description

Now we have parse the whole JSON value into the JSON type, but then you have a lot of overhead when you have a lot of properties that you don't use. I tried this with a type DecodableValue that has a helper method to cast the data of the DecodableValue to the type that you want. DecodableValue replaces JSON and also saves a lot of looping and switches.

Contributor guide

Research direction
Investigate implementing lazy decoding in Argo by introducing a DecodableValue type that delays type casting until the value is accessed, reducing overhead for unused properties.
