What does JSON stand for?

JSON stands for JavaScript Object Notation. It is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. The name reflects the fact that it is based on a subset of the JavaScript programming language, specifically the way objects are represented within JavaScript. JSON is widely used for transmitting data in web applications between a server and a client, as it serves as a common format that many programming languages can easily work with.

Other choices provide alternative interpretations that do not accurately represent what JSON stands for. For instance, the terms ‘Online Notation,’ ‘Java Syntax Object Notation,’ and ‘Standard Output Notation’ do not convey the essence of JSON as a structured way of representing data similar to JavaScript objects. This clarity is why the correct answer effectively captures the fundamental nature of JSON.
