What is JSON?

JSON, or JavaScript Object Notation, is a lightweight data-interchange format that is easy for humans to read and write. It is easy for machines to parse and generate. Derived from the JavaScript programming language, JSON has become the universal standard for structured data exchange across the web and various software systems.

Its design emphasizes simplicity and interoperability, making it language-independent despite its roots in JavaScript. This universality allows developers to transmit data between servers and clients seamlessly, regardless of the underlying technology stack. The format relies on text, which ensures transparency and ease of debugging during development processes.

Commonly used in web APIs, configuration files, and NoSQL databases, JSON supports hierarchical data structures through objects and arrays. Its widespread adoption is driven by native support in modern programming languages and web browsers. As a result, it remains the preferred choice for transmitting structured information in the digital ecosystem.
