Understanding the difference between YAML and JSON, and when to use each format.
What is YAML?
YAML (YAML Ain't Markup Language) is a human-friendly data serialization format widely used for couration files, CI/CD pipelines, and infrastructure-as-code tools like Kubernetes and Docker Compose. Its indentation-based syntax makes it easy to read and write.
What is JSON?
JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. Converting YAML to JSON produces a format that is universally supported across all programming languages and tools, making it easier to integrate with APIs and web services.
