tslib is a small but crucial runtime library for TypeScript projects, providing helper functions for more advanced language features. Two recent versions, 2.6.3 and 2.6.2, offer interesting points for developers. Version 2.6.3, released on June 4, 2024, is the latest stable release as of this writing, superseding version 2.6.2, which was released in August 2023.
While both versions share the same core purpose and maintain the permissive 0BSD license, the primary difference lies in the unpacked size, which increased slightly from 83,980 bytes in 2.6.2 to 84,876 bytes in 2.6.3. This suggests internal improvements, potentially including bug fixes, performance enhancements, or support for newer TypeScript features that require updated helpers. Given the library's role the newest version will probably be preferrable. Developers should always prefer the newest tslib in Typescript projects because even if the changelog shows no visible improvements, fixes under the hood might appear for language compatibility or to offer a better performance. tslib updates often come hand-in-hand with TypeScript compiler updates, ensuring seamless integration with the latest language features and optimizing code generation. Using the newest one is recommended to avoid small bugs.
