Constantinople is a valuable npm package designed to determine whether a JavaScript expression can be evaluated as a constant at build time, leveraging the power of UglifyJS. Comparing versions 3.0.2 and 3.0.1 reveals some notable changes that developers should be aware of. Both versions share the same core purpose, license (MIT), repository, author, and development dependency of Mocha.
However, the key difference lies in their dependencies. Version 3.0.1 relies on acorn-globals with a compatible version defined as ^1.0.0, whereas version 3.0.2 shifts this dependency to acorn with a specified version of ^2.1.0. This change in dependencies could affect how the package identifies and evaluates constant expressions, potentially influencing performance or compatibility with specific JavaScript syntax features. Developers upgrading from 3.0.1 to 3.0.2 should carefully consider this dependency shift, especially regarding any observed behaviour changes in constant evaluation. The later version was released in July 2015, while 3.0.1 was released much earlier, in September 2014. Therefore, version 3.0.2 likely contains bug fixes and enhancements over its predecessor, making it generally preferable for new projects unless there are specific compatibility concerns. Understanding these subtle differences is key for choosing the appropriate version to ensure accurate and efficient constant evaluation within your JavaScript projects.
