ReasonML Basics: Functions and Float Arithmetic

ReasonML combines the robust type safety of the OCaml ecosystem with a developer-friendly syntax. If you want to write highly predictable, bulletproof web applications, mastering how ReasonML handles basic functions and numeric types is your essential first step. This text-based course guides you through the foundational concepts of the language, using practical mathematical conversions to solidify your understanding. You will transition from writing simple expressions to structuring clean, reusable functions that handle strict type constraints with ease. By working through hands-on logic exercises, you will develop a strong mental model for how type inference and pure functions behave in a modern functional programming environment. What you'll learn: - Understand the core syntax, type system, and foundational concepts of ReasonML - Declare and execute functions using modern functional programming patterns - Perform precise float arithmetic and manage strict type conversions without errors - Leverage type inference to write cleaner, more concise code - Implement practical conversion formulas as robust, reusable functions - Practice debugging type mismatch errors in a structured, step-by-step manner This course begins with a clear introduction to ReasonML terminology, basic syntax, and type definitions. You will then progress to writing your first functions, handling decimal numbers, and solving practical conversion challenges using written explanations and code examples. This course is designed for beginners who are new to ReasonML or functional programming. No prior experience with OCaml or advanced mathematics is required.
