babel-plugin-transform-class-properties enables the use of class properties syntax in JavaScript. It transforms class field declarations, both with and without initial values, into equivalent constructor or static class blocks syntax supported by the target environment. This allows developers to use a more concise and readable way to define properties directly within a class. The plugin ensures cross-browser compatibility by converting modern class property syntax into code understandable by older JavaScript engines.

Since then, there have been no new versions published, indicating the package is likely no longer actively maintained as of August 2025.
