What is JSON?
JSON (JavaScript Object Notation) is a lightweight data exchange format that is language-independent. It uses human-readable text format, is self-descriptive and easy to understand.
Although JSON was originally evolved from JavaScript by Douglas Crockford, nowadays almost all modern programming languages can generate and parse JSON data.
As the mainstream data format for asynchronous communication between browsers and servers, JSON has replaced XML in many AJAX systems. Compared to XML, it's more concise and easier to parse.
On the Internet, the official content type for JSON is application/json
. When JSON is used as
the data exchange format, browsers and servers set the Content-Type HTTP header to
application/json
.
