A practical comparison of JSON and YAML for APIs, configs, docs, and developer tools.
JSON is strict, predictable, and widely used for APIs. YAML is easier to read for configuration files, but indentation and implicit types can create mistakes.
Use JSON when machines are the primary reader. Use YAML when humans edit configuration often and the project already expects YAML.
