mapMaybeIntfn

mapMaybeIntfn is a functional programming utility that applies a specified function to elements of a list or collection, particularly focusing on integer values. The primary purpose of mapMaybeIntfn is to transform each element of a collection according to a given function that may or may not produce a result, effectively combining mapping and filtering operations.

This function takes as input a collection (such as a list or array) and a mapping function that returns an optional value, often represented as a Maybe or Option type. When the function returns a valid value, it is included in the resulting collection; if it returns nothing (or null/none), that element is excluded, enabling concise filtering during mapping.

mapMaybeIntfn is commonly used in scenarios where transformations may fail or be optional, allowing developers to process collections efficiently without explicitly filtering out invalid results afterward. It streamlines code by combining the mapping and filtering steps into one operation.

Various programming languages include similar constructs or functions under different names. For example, in Haskell, the combination of map and catMaybes achieves this behavior. In functional JavaScript or TypeScript, custom implementations or utility libraries may define such functions. Their implementations typically involve iterating over the collection, applying the function to each element, and collecting only those results that are valid.

Overall, mapMaybeIntfn is a valuable tool in functional programming paradigms, supporting safe and concise data transformation workflows, especially when dealing with optional or potentially missing data in collections.
