Dayjs, a lightweight and immutable date-time library, offers a compelling alternative to Moment.js with its modern API and tiny footprint, typically around 2KB. Versions 1.8.14 and 1.8.15 are quite similar, sharing the same core purpose and developer dependencies for testing and building. Both versions include tools like jest for testing, rollup for bundling, and eslint for code linting, ensuring code quality and a smooth development experience. They also rely on Babel for transpilation, supporting a wide range of JavaScript environments.
The key difference lies in the unpackedSize of the distributed package and the release date. Version 1.8.15, released on July 8, 2019, has an unpacked size of 389037 bytes, slightly larger than version 1.8.14 at 387226 bytes, released on May 7, 2019. This small increase suggests potential bug fixes, minor feature additions, or updates to internal tooling. For developers, upgrading to 1.8.15 is generally recommended to benefit from the latest improvements and stability enhancements. If you are experiencing issues with date manipulations in version 1.8.14, upgrading to 1.8.15 should be considered. The library is under the MIT license so you can include it without major restrictions in your projects.
