TypeScript Utility Types Collection

utility-types is a comprehensive collection of TypeScript utility types designed to complement and extend TypeScript's built-in mapped types and aliases. Currently stable at v3.11.0, the library maintains an active release schedule, frequently introducing new type utilities and refining existing ones to keep pace with TypeScript's evolution and community needs. It differentiates itself by offering a broad range of idiomatic types, including those compatible with Flow's utility types to aid migration efforts, all without introducing any runtime cost. The package prides itself on being secure and minimal, having no third-party dependencies and ensuring type correctness through rigorous testing with `dts-jest`. Its primary goal is to provide developers with a robust, zero-cost 'lodash' for static types, eliminating the need to re-implement common type patterns across projects.
