About this course

ReasonML combines the speed and safety of OCaml with a highly readable syntax, but mastering its strict type system starts with the absolute basics. Working with numbers in a strongly typed functional language requires a precise understanding of how data is represented in memory. This course helps you build a rock-solid foundation in ReasonML by focusing on how integers function under the hood. By reading this guide, you will transition from writing basic expressions to confidently managing type safety and numeric operations in functional applications. You will explore how ReasonML handles integer limits, memory allocation, and strict type compiler rules without unexpected runtime errors. What you'll learn: - Understand the core definition and foundational concepts of the integer data type in ReasonML - Manage memory allocation and understand the bit-size limits of integers in functional compilation - Apply basic and advanced arithmetic operators specifically designed for integer calculations - Practice type annotations and explicit casting to prevent compiler errors during development - Master modern type inference patterns to write cleaner and more concise functional code This course begins with essential terminology, defining what integers are and how the ReasonML compiler interprets them. You will then progress through interactive code examples that demonstrate arithmetic operations, type safety rules, and common compiler warnings. This course is designed entirely for beginners who are new to ReasonML or functional programming, requiring no prior experience with strongly typed languages. Read on to start writing safer, faster code today.
