babel-plugin-transform-class-constructor-call is a Babel plugin that transforms class constructor calls into normal function calls. This enables more flexible dependency injection and mocking during testing, particularly when dealing with classes that perform significant setup in their constructors. By converting new MyClass() to a standard function call, the plugin allows for easier interception and manipulation of the instantiation process via techniques like proxying or stubbing. Ultimately, this plugin enhances the testability and maintainability of JavaScript codebases utilizing modern class syntax.
