In YAML there are three types data types:
- Scalars: Scalars are values like Strings, Integers, Booleans, etc.
- Sequences: Sequences are lists with each item starting with a hyphen (
-). Lists can also be nested.
- Mappings: Mapping gives the ability to list keys with values. They are like dictionaries or hash maps.
Each datatype will be discussed in detail in next chapters.
