YAML (short for “YAML Ain’t Markup Language”) is a human-readable data serialization language that is often used for configuration files and data exchange between applications. It is designed to be easy to read and write by humans, with a focus on being simple, clear, and concise.
YAML is often used in web development, especially with the rise of containerization and DevOps practices, where it can be used for defining application configurations and deployment instructions. It can also be used for storing structured data, such as JSON or XML, in a more readable format.
Some key features of YAML include:
- Indentation-based structure: YAML uses whitespace indentation to indicate nested levels of data, making it easy to read and understand.
- Support for multiple data types: YAML supports basic data types like strings, numbers, and booleans, as well as more complex types like arrays and maps.
- Comments: YAML supports comments, which can be used to provide additional context or explanations for the data.
- Extensible syntax: YAML is designed to be extensible, meaning that developers can define their own custom data types and structures.
Overall, YAML is a flexible and powerful tool for managing data and configurations, and has become a popular choice for many developers and organizations.
