Ruby on Rails (uses YAML for configuration)

Ruby on Rails is a web application framework that helps developers build websites and online services more efficiently by providing a structured environment. It emphasizes convention over configuration, meaning it follows set guidelines to simplify coding, making it easier to develop complex applications. One of the components is YAML (Yet Another Markup Language), a human-readable data format used for configuration files. This allows developers to easily manage and configure application settings in a straightforward way, enhancing collaboration and reducing errors during development. Overall, Rails streamlines web development, enabling faster and more organized project creation.
