Question 4

What is the difference between JSON and YAML?

Accepted Answer

JSON (JavaScript Object Notation) uses braces and brackets with strict syntax, while YAML (YAML Ain't Markup Language) uses indentation and is more human-readable. YAML supports comments, multiline strings, and anchors. JSON is preferred for APIs and data interchange, while YAML is popular for configuration files like Docker Compose, Kubernetes, and CI/CD pipelines.
