What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is language-independent and has become one of the most popular data formats used for transmitting data in web applications, particularly in APIs and configuration files.

JSON Formatting Best Practices

  • Use consistent indentation (2 or 4 spaces)
  • Place each property on a new line for better readability
  • Use quotes around property names (required by JSON specification)
  • Validate JSON syntax before using in production
  • Minify JSON when network performance is crucial
  • Include appropriate content-type headers when serving JSON
