YAML, like many other data serialization languages (such as JSON), has very few, basic concepts:
- Declarations
- Lists
- Associative arrays
A declaration is very similar to a variable in any other language, which is as follows:
name: 'This is the name'
To create a list, we will have to use -:
- 'item1'
- 'item2'
- 'item3'
YAML uses indentation to logically divide parents from children. So, if we want to create associative arrays (also known as objects), we would just need to add an indentation:
item:
name: TheName
location: TheLocation
Obviously, we can mix those together as follows:
people:
- name: Albert
number: +1000000000
country: USA
- name: David
number: +44000000000
country: UK
Those are the basics of YAML. YAML can do much more, but for now, this will be enough.
