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, yml, Yet Another Markup Language

Why learn YAML?

Developers should learn YAML for writing configuration files in tools like Docker, Kubernetes, Ansible, and CI/CD pipelines, as it's widely adopted in DevOps and infrastructure-as-code contexts. It's also useful for data serialization in applications that require human-editable data formats, such as settings files or API specifications, due to its clarity and minimal syntax compared to JSON or XML.
