What is the purpose of the "dw.json" module in Salesforce B2C Commerce?

The "dw.json" module in Salesforce B2C Commerce is primarily used to handle JSON data input and output. JSON (JavaScript Object Notation) is a widely used data format that allows for easy data interchange, particularly between a server and a web application. The module provides functionality to parse JSON strings into JavaScript objects, enabling developers to work with the data easily within their applications. Conversely, it also allows for the conversion of JavaScript objects back into JSON strings, facilitating the output of structured data for APIs and other interfaces.

This capability is crucial in modern web development, where many applications utilize JSON for configuration, data transfer, and communication between client and server. By standardizing how JSON is handled, the "dw.json" module allows developers to focus on the business logic of their applications without worrying about the complexities of JSON parsing and serialization.
