The DynamicSchema gem provides a elegant and expressive way to define a domain-specific language (DSL) schemas, making it effortless to build and validate complex Ruby hashes. This is particularly useful when dealing with intricate configurations or interfacing with external APIs, where data structures need to adhere to specific formats and validations. By allowing default values, type constraints, nested schemas, and transformations, DynamicSchema ensures that your data structures are both robust and flexible.
