YAML vs JSON
Both YAML and JSON are data serialization formats. JSON uses braces and brackets and is the standard for APIs. YAML uses indentation and is more human-readable, commonly used for configuration files in Docker, Kubernetes, GitHub Actions, and CI/CD pipelines. Converting between them is a frequent task for developers and DevOps engineers.
