What is JSON?

JavaScript Object Notation has become the universal language of data exchange. After two decades of use, JSON remains the preferred format for APIs, configuration files, and data storage across the entire software industry.

Why JSON Dominates

Unlike its predecessors, JSON offers human-readable syntax, native JavaScript support, and parsing performance that revolutionized web development. The simplicity that critics once mocked became its greatest strength.

Best Practices

Always validate JSON before transmission. Use consistent formatting tools. Understand the difference between JSON and JavaScript object literals. These fundamentals separate professional developers from hobbyists.
