A lightweight texting, open, standard for human-reading information exchange is a JSON or JavaScript Object Notation. Douglas Crockford originally proposed and detailed the JSON format in RFC 4627. JSON's official Internet media type is app/json. The extension of the JSON filename is .json. It helps you grasp JSON's use in various programming languages like PHP, PERL, Python, Ruby, Java, etc.

  • It is used in building apps based on JavaScript, which includes website and browser plugins.
  • JSON format is utilized for the serialization and transmission of structured data via a network connection.
  • It is mostly used for transmitting data from servers to web applications.
  • JSON is used to give public data by web services and APIs.
  • It can be utilized with modern languages of programming.

The JSON features

  • JSON reads and writes easily.
  • It's a small text-based format for interchange.
  • JSON is independent of language.

This lesson was meant to help novices grasp JavaScript Object Notation's features for developing the data exchange format. You have an excellent grasp of JSON and how JavaScript, Ajax, Perl, etc., will be used after completing this tutorial.

You should have a fundamental understanding of the work of the web application over HTTP before you begin with this tutorial, and we expect you to have basic JavaScript expertise.
