JSON (JavaScript Object Notation)

A standard text format used to store and send data between computers and websites.

Detailed Explanation

JSON (JavaScript Object Notation) is an open standard file format and data interchange format (RFC 8259) that uses human-readable text to store and transmit data objects consisting of attribute-value pairs and arrays. It is language-independent and the primary data serialization format utilized by modern web APIs, microservices, and configuration files. You can test this using the JSON Toolkit.

Key Technical Takeaways

  • Built upon two primary data structures: collections of key/value pairs (objects) and ordered lists of values (arrays).
  • Requires double quotes for string keys and values.
  • Strict syntax does not permit trailing commas in standard specification.
  • Lightweight and natively parsable across virtually all modern programming languages.
