https://github.com/mattpocock/ts-resetA library that improves TypeScript's built-in typings for common JavaScript APIs, similar to a CSS reset. It provides safer type handling for JSON.parse() and fetch responses by returning unknown instead of any, fixes type narrowing for .filter(Boolean), and improves ergonomics for array.includes on readonly arrays.
ts-reset modifies several built-in behaviors to improve type safety and ergonomics:
.json() (on fetch responses) and JSON.parse() to return unknown instead of any, forcing safer type handling..filter(Boolean) so it behaves as expected by correctly narrowing types (e.g., removing null/undefined/falsy values from the resulting type).array.includes to be more ergonomic, specifically addressing issues where it often fails on readonly arrays.
