JSON vs YAML: Syntax, Performance, Readability & Use Cases

JSON is the strict, bracket-heavy standard for web API data payloads. YAML is an indentation-sensitive superset of JSON designed specifically for human-readable DevOps configuration files.

Architectural Verdict

Use JSON for API serialization and machine-to-machine transmission. Use YAML for human-edited configuration files, infrastructure-as-code, and CI/CD pipelines.
