YAML vs JSON

Basically, both JSON and YAML were developed to provide a human-readable data interchange format.

YAML is implemented as a superset of the JSON format. This means that we can parse JSON using a YAML parser.

The following are some key differences between YAML and JSON:

YAML	JSON
Complex and time consuming process of parsing Serialized data	Quickly and easily parse JSON serialized data with its simpler design
Less community support	Larger community support and popularity
Supports comments	Doesn’t support comments
Ability to use reference of other data objects	Impossible to serialize complex structures with object references
Hierarchy is denoted by using double space characters. Tab characters are not allowed	Objects and Arrays are denoted in braces and brackets.
String quotes are optional but it supports single and double quotes.	Strings must be in double quotes.
Root node can be any of the valid data types	Root node must either be an array or an object.
