HC13-13. Haskell Chapter 13 Practical Tasks: Modules |
This lesson introduces modules in Haskell, essential for organizing, structuring, and reusing code effectively. It starts with importing modules, explaining how to access predefined functionality from Haskell’s extensive libraries. Managing environments and namespaces is crucial, so the lesson covers techniques for controlling which functions and types are imported, avoiding conflicts, and maintaining clarity. After understanding how to use existing modules, the lesson moves on to creating our own modules, demonstrating how to define, export, and structure code efficiently. A key part of the lesson explores The Prelude and Standard Libraries, the foundational modules that provide essential functions without requiring explicit imports. Throughout, learners are encouraged to leverage both video and written materials, as each format offers unique advantages—video for live refactoring demonstrations and written explanations for structured, sequential learning. By mastering modules, developers gain the ability to build scalable and maintainable Haskell programs. |
