Strickland is not a bloated collection of validators. Instead, Strickland is an extensible framework on which you can build your application's validation. To achieve the extensibility goal, Strickland keeps its core concepts at a minimum and provides you with the power to extend the concepts as needed in your application.
We learned that Strickland is made up of three core concepts: Validators, Validation, and Validation Results. All three of these concepts are extensible.
With validator factories, validation context, and validation result props, even the simplest validators can become extremely extensible. When combining these features, an extensibility pattern emerges.
