What does JSON stand for?

The correct choice is JavaScript Object Notation. JSON is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is primarily used to transmit data between a server and a web application, as an alternative to XML. JSON's syntax is derived from JavaScript object notation, making it integral to web development, particularly when working with APIs that return data in this format.

This term emphasizes how JSON structures data in a way that mirrors JavaScript objects, consisting of key-value pairs. Its simplicity and ease of integration with JavaScript environments have contributed to its widespread adoption across many programming languages and platforms.

Other options presented do not accurately describe JSON: "JavaScript Open Network" and "JavaScript Organized Node" do not relate to the data format, while "Java Source Object Notation" is incorrect as it mistakenly incorporates Java, which is separate from the origin of JSON's name.
