Intersection Types

Intersection types are a concept in type theory, particularly in programming languages, that allow a value to belong to multiple types simultaneously. Think of it as a person who is both a teacher and a musician; they have characteristics of both roles. In programming, this means a variable can hold values that conform to more than one type, enhancing flexibility and reusability. For example, a function that accepts inputs that are both numeric and iterable can perform operations on them as if they belong to both categories, making code more robust and adaptable.
