Abstract-JavaScript is a dynamic, weakly typed, multiparadigm programming language that supports object-oriented, imperative, and functional programming styles. While web developers appreciate this flexibility when implementing complex and interactive web applications, this wide range of possible styles can hinder program comprehension and make maintenance difficult, especially in large projects involving many different programmers. A particular problem is the several different ways in which object-oriented classes can be expressed in JavaScript. In this work we aim at enhancing the maintainability of objectoriented JavaScript applications by automatically normalizing the representation of classes to a single model.
