JSON has an advantage over XML since it has a map data structure that corresponds to the actual data, making interpretation easier and data layout more predictable. The JSON data structure aids in the development of RESTful APIs by simplifying data exchange mechanisms. The same data representation approach is used in JSON as it is in code.
