YAML and JSON explained
What is a YAML file?
YAML is a human friendly data format often used for configuration. Its clean, indentation based syntax makes it easy to read and edit by hand.
What is a JSON file?
JSON is the standard data format for the web and APIs. It stores structured data as human readable key value pairs and arrays, and is supported by every modern programming language.
