JSON: JavaScript Object Notation

The video tutorial introduces JSON as a nonproprietary data structure commonly used in APIs. It demonstrates a weather application that fetches live data from an API in JSON format. The tutorial explains the code structure, including HTML and JavaScript components, and how to parse JSON data. It also covers creating and displaying HTML dynamically using JSON data and highlights the use of helper functions for data conversion. The video concludes with a brief mention of XML as another data structuring method.
