JSON characteristics include the following:
- Flexibility, allowing the programmer to define keys.
- Less overhead, as content is mostly data.
- Portable data.
- Common and convenient format for Web services.
Commonly utilized in Web application development, JSON may be used as a data format for any application where information is stored as text.
JSON is preferred by some over XML as a data exchange format because it is less verbose, works quickly, reduces data size and simplifies document processing. It is used extensively in web development, especially because it seamlessly transfers information between potentially incompatible technologies. For example, it could involve a Java application running on a UNIX box or a C# application running on Windows.
