TypeScript Helper Types Collection

helpertypes is a lightweight collection of general-purpose TypeScript helper types designed to simplify complex type manipulations across various projects. As of version `0.0.19`, the library offers utilities like deep partial/required types, object key pickers, and string lookup types. The project maintains an active development status, with frequent releases (often multiple per month) focused on introducing new helper types and refining the behavior and robustness of existing ones, particularly for deep type transformations. Its key differentiators include its small footprint, focused scope on just type utilities without runtime code, and a commitment to providing common, reusable type patterns that might otherwise be cumbersome to implement from scratch. While still in a pre-1.0 state, it's regularly updated with fixes and new features.
