Which data format is used in this script?

API
JSON
JavaScript
YANG

The correct answer is: JSON

The data format used in the script being referred to is JSON (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 widely used for transmitting data in web applications, particularly in scenarios involving communication between a client and a server. In many scripts involving data exchange, particularly within web services and APIs, JSON serves as a standard due to its simplicity and compatibility with most programming languages, including JavaScript. This format is structured using key-value pairs, which makes it intuitive to work with, especially for those familiar with JavaScript object syntax. To provide further context, while the term API refers to an interface for interaction with software components and might utilize JSON as its data format, it is not a specific data format itself. Similarly, JavaScript is a programming language that can manipulate JSON data but does not constitute a data format. YANG is a data modeling language used primarily for network configuration in conjunction with NETCONF, which is distinct from the typical data formats encountered in general scripting and API interactions. Thus, the correct identification of JSON represents an accurate understanding of the scripting context.
