This is a guide to applying functional programming techniques to domain modeling, emphasizing how to create accurate, maintainable, and testable systems. It introduces core concepts of functional programming and demonstrates how to model complex domains effectively. The book covers topics such as algebraic data types, immutability, and composition. Real-world examples and practical exercises are used to guide readers. It aims to enhance software architecture and improve code quality through functional design principles.
This book provides a hands-on introduction to test-driven development (TDD), a software development process that emphasizes writing automated tests before coding. Through practical examples, Kent Beck demonstrates how TDD can lead to cleaner, more reliable code by encouraging simple designs and continuous refactoring. The book follows two TDD projects from start to finish, showcasing techniques for increasing the quality of software development.
On this episode of the Distributed podcast, host Jack Hannah talks with James Simone, Principal Engineer at Salesforce, about how he went from no development experience to principal engineer in 7 years at a Fortune 500 and the effects of collaborative programming.
