What is enumeration and type deaf?

Enumeration is a programming concept where a variable can hold a set of predefined constants, typically used to represent a collection of related values in a more readable way. In certain programming languages, an "enum" (short for enumeration) defines a type that consists of a set of named values. "Type deaf" is not a standard term in programming; it may refer to a lack of awareness or inability to recognize data types in certain contexts, which can lead to errors or misinterpretations in code.
