Tool-Supported Refactoring for JavaScript

Free registration required

Executive Summary

Refactoring is a popular technique for improving the structure of existing programs while maintaining their behavior. For statically typed programming languages such as Java, a wide variety of refactorings have been described, and tool support for performing refactorings and ensuring their correctness is widely available in modern IDEs. For the JavaScript programming language, however, existing refactoring tools are less mature and often unable to ensure that program behavior is preserved. Refactoring algorithms that have been developed for statically typed languages are not applicable to JavaScript because of its dynamic nature.
