JSON was first proposed by Douglas Crockford in 2002, but it didn’t gain widespread popularity until around 2005, when it began to be used as an alternative to XML in AJAX-style web applications.
JSON’s main benefits compared to XML include:
- It is less verbose and less cluttered, making it easier to read and write.
- It is easier for computers to parse and generate, making it more efficient for data transfer.
Some examples of commonly used JSON applications include:
- Sending and receiving data between a web server and a web application
- Storing and exchanging data between mobile apps and servers
- Configuration files in software projects
- RESTful APIs and data transfer between microservices
JSON is widely used in many modern application stacks, and it is supported by almost all modern web browsers, servers and database systems.
