What is JSON Web Services?

JSON Web Services is a somewhat outdated term that generally refers to using JSON as the format for data exchange in web services, as opposed to XML (which was common with SOAP-based web services). It encompasses a collection of technologies and standards for building web services that communicate using JSON. Common uses include creating APIs for web applications, mobile apps, and other services to exchange data in a lightweight, human-readable format. While the term 'JSON Web Services' is less prevalent now, the underlying concept of using JSON for data exchange in APIs remains extremely common, particularly with RESTful APIs.
