Date-fns is a modern JavaScript date utility library designed to simplify date manipulation and formatting in web applications. Versions 1.21.0 and 1.21.1 represent minor updates within the 1.x release line, primarily focusing on bug fixes and incremental improvements rather than introducing significant new features. Developers already familiar with date-fns will find the upgrade straightforward, with no breaking API changes between these versions.
The primary difference lies in the release date, with version 1.21.1 being published two days after 1.21.0. This suggests that 1.21.1 likely addresses issues discovered shortly after the release of 1.21.0. For developers, this means updating to the latest patch version (1.21.1) is recommended to benefit from the most stable and reliable code. Both versions share identical dependencies and devDependencies, indicating no changes in the tooling or testing environment.
Date-fns distinguishes itself with its modular design, allowing developers to import only the specific functions they need, reducing bundle size and improving performance. Furthermore, its focus on immutability ensures that date operations do not modify the original date objects, preventing unexpected side effects. While these two specific versions offer incremental improvements, the core value proposition of date-fns – its modern approach, modularity, and immutability – remains consistent, making it a compelling choice for JavaScript date handling. Both are under the MIT license, with source code maintained and released publicly.
