YAML

YAML (YAML Ain't Markup Language) is a human-readable data serialization language commonly used for configuration files, data exchange, and storing structured data. It uses indentation and simple syntax to represent data structures like lists, dictionaries, and scalars, making it easy for humans to read and write while being parsable by machines.

Also known as: YAML Ain't Markup Language, YML, Yaml, Yet Another Markup Language, YAML serialization

Why learn YAML?

Developers should learn YAML for configuration management in tools like Docker, Kubernetes, and Ansible, as well as for data serialization in applications that require human-editable settings. It's particularly useful in DevOps, cloud infrastructure, and CI/CD pipelines where readability and simplicity are prioritized over complex markup.
