What is JSON?
- JSON stands for JavaScript Object Notation
- JSON is a lightweight data-interchange format
- JSON is "self-describing" and easy to understand
- JSON is language independent *
JSON uses JavaScript syntax, but the JSON format is text only.
Text can be read and used as a data format by any programming language.
Why use JSON?
Since the JSON format is text only, it can easily be sent to and from a server, and used as a data format by any programming language.
JavaScript has a built in function to convert a string, written in JSON format, into native JavaScript objects:
JSON.parse()
So, if you receive data from a server, in JSON format, you can use it like any other JavaScript object.
