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 to denote structure and supports scalars, sequences, and mappings, making it easy to write and read for both humans and machines.

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

Why learn YAML?

Developers should learn YAML for creating configuration files in tools like Docker, Kubernetes, and Ansible, as it is widely adopted in DevOps and infrastructure-as-code workflows. It is also useful for data serialization in applications that require simple, readable formats, such as API specifications with OpenAPI or CI/CD pipelines in GitHub Actions.
