ActiveSupportJSON

ActiveSupportJSON is a component of the Ruby on Rails framework, specifically within the Active Support library. Its primary function is to enhance the handling of JSON data within Ruby applications. It provides extensions and utilities that make it easier to serialize Ruby objects into JSON format and to parse JSON strings back into Ruby objects.

One of the key features of ActiveSupportJSON is its ability to serialize complex Ruby objects, such as Active Record models, into JSON. This often involves custom serialization logic to control which attributes are included and how they are formatted. It also provides methods for encoding Ruby data structures, like hashes and arrays, into JSON strings.

Conversely, ActiveSupportJSON offers utilities for parsing JSON strings into their corresponding Ruby representations. This allows developers to seamlessly integrate external JSON data into their applications. The library aims to simplify common JSON manipulation tasks, reducing the amount of boilerplate code required and improving the developer experience when working with JSON data in Ruby. It's an integral part of how Rails applications interact with APIs and manage data serialization.
