Polymorphic Functions

Explore how to define and use polymorphic functions in ReasonML, allowing a single function to operate with various data types. Understand type variables, how they simplify code, and improve function flexibility while maintaining strong typing.

Polymorphic functions are functions that work with several data types.

Since Reason is a strongly-typed language, we often explicitly define the type of our values.

Applying this rule to function parameters, we would end up with the same function being redefined again and again ...
