What is YAML?

YAML (YAML Ain't Markup Language) is a lightweight data-interchange format. It's easy for humans to read and write, and easy for machines to parse and generate. YAML is built on two structures:

1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
2. An ordered list of values (e.g., `["apple", "banana", "cherry"]`). In most languages, this is realized as an array, vector, list, or sequence.

YAML is widely used in web applications for sending data between a server and web browser, as an alternative to XML.
