About JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.

Common uses:

  • Transmitting data between a server and web application
  • Configuration files
  • Storing structured data
  • API responses

JSON Syntax Rules:

  • Data is in name/value pairs
  • Data is separated by commas
  • Curly braces hold objects
  • Square brackets hold arrays
