## Description

go-funk is a functional programming library for Go that provides a set of helper functions to transform and query slices and maps. It enables a declarative coding style for collection manipulation and data transformation, reducing the need for repetitive manual loops.

The library implements higher-order functions for common operations, including mapping, filtering, and searching through data structures using predicates and callbacks. It includes utilities for detecting element existence and finding common elements between collections.

These capabilities are supported through generic-based type constraints and interface-driven type assertions to ensure operations work across diverse element types.
