Master common data transformations using functional programming patterns in TypeScript. This guide covers essential techniques for arrays, objects, and complex data structures, including mapping, filtering, reducing, grouping, and safely accessing nested values. It teaches how to replace verbose, imperative loops with concise, declarative functional code, improving readability and maintainability.

A comprehensive, generics-first utility library inspired by Lodash, providing 500+ type-safe functions for Go collections. It enables highly declarative and functional programming patterns (Map, Filter, Reduce, GroupBy) over slices, maps, and strings, eliminating manual boilerplate loops. It supports immutable operations, concurrent processing (lop), and lazy iteration (loi) for advanced, efficient data transformations.
