What is JSON?

  • Refers JSON JavaScript Object Notation
  • JSON is a lightweight text data interchange format
  • JSON is language independent: JSON uses Javascript syntax to describe data objects, but JSON is still language and platform independent. The JSON parser and JSON library support many different programming languages. Currently, many dynamic (PHP, JSP, .NET) programming languages ​​support JSON.
  • JSON is self-describing and easier to understand
