better-typescript-lib

An alternative TypeScript standard library that replaces TypeScript's built-in type definitions with safer, more precise types. Version 2.12.0 supports TypeScript 4.5+ (up to 5.8). It fixes many `any` usages in the standard library (e.g., JSON.parse returns `JSONData` instead of `any`, Object.keys returns `(keyof T)[]` instead of `string[]`). Aimed at new projects or codebases willing to accept breaking changes for improved type safety. No configuration needed for npm/yarn (auto-detected); pnpm requires public hoist pattern. The package replaces `@typescript/lib-*` packages via npm's scoped package mapping.
