LEARNING OBJECTIVES
- Identify benefits of ReasonML static typing and how it differs from JavaScript type checking
- Apply operators and precedence to perform arithmetic, comparison, and logical operations
- Use core data types and conversions (int, float, bool, char, string) while avoiding type errors
- Create identifiers with let bindings, type annotations, scope control, and ref-based mutability
- Construct and manipulate tuples, records, and arrays using pattern matching and mutation techniques
- Write functions using currying, recursion, labels, polymorphism, and functions as values
- Build variants, option types, lists, and objects, using switch-based pattern matching to handle cases
