ReasonML Programming Foundations and Data Types

ReasonML combines the safety and speed of OCaml with a developer-friendly syntax, making it an excellent choice for modern web and systems development. To write reliable code, you must first master how it handles and validates data. This text-based course guides you through the fundamental building blocks of ReasonML so you can write predictable, type-safe applications from scratch. By completing this course, you will transition from a beginner to a confident programmer who understands how the ReasonML type system prevents runtime errors. You will practice reading and analyzing code snippets, identifying type mismatches, and structuring functional data structures. What you'll learn: - Understand foundational concepts of strongly typed functional programming - Master core primitive types including integers, floats, strings, and booleans - Apply pattern matching to safely destructure and evaluate complex data - Configure and use variant types and options to handle null-like scenarios safely - Practice debugging type errors through written code analysis and self-assessments - Explore modern compilation workflows to see how ReasonML targets JavaScript This course begins with essential terminology, defining static typing and the core philosophy of ReasonML. You will then progress through detailed written lessons on each major data type, complete with realistic code examples, syntax breakdowns, and conceptual quizzes to test your understanding. This course is designed for beginners who are new to ReasonML or functional programming. No prior experience with OCaml or type systems is required.
