UglifyJS version 3.15.5 represents a minor update over its predecessor, version 3.15.4, in this popular JavaScript minification toolkit. Both versions maintain the core functionality of parsing, mangling, compressing, and beautifying JavaScript code, crucial for optimizing web application performance. Developers familiar with UglifyJS will find the familiar BSD-2-Clause license, repository on GitHub, and authorship details unchanged.
The primary difference lies in the "dist" section of the package metadata. Version 3.15.5 has a slightly larger unpacked size of 1,238,767 bytes compared to 3.15.4's 1,238,049 bytes, indicating minor additions or adjustments to the codebase. The file count remains consistent at 20. This suggests that the update may incorporate bug fixes, performance improvements, or small feature enhancements rather than a major overhaul. The later releaseDate for v3.15.5, specifically May 10, 2022, versus April 9, 2022 for v3.15.4, confirms it as a more recent release.
For developers already using UglifyJS, upgrading to 3.15.5 is likely a low-risk proposition, potentially offering subtle improvements and refinements. Those new to UglifyJS can confidently use either version, as the core functionality remains consistent, with 3.15.5 being the preferred choice due to its recency. Both rely on the same versions of acorn and semver.
