Pattern Matching
Explore how to use pattern matching in ReasonML to destructure tuples and access their components. Learn to create patterns with identifiers that correspond to tuple values and use the underscore to ignore unneeded elements. This lesson helps you understand accessing tuple data effectively within ReasonML's immutable data structures.
