What is JSON

• JSON (JavaScript Object Notation) is a lightweight data-interchange format.
• It is easy for humans to read and write.
• It is easy for machines to parse and generate.
• It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999.
• JSON is a text format that is completely language independent but uses conventions that are familiar to programmers.
• These properties make JSON an ideal data-interchange language.
