Refactoring Legacy JavaScript Code to Use Classes: The Good, The Bad and The Ugly

JavaScript systems are becoming increasingly complex and large. To tackle the challenges involved in implementing these systems, the language is evolving to include several constructions for programmingin-the-large. For example, although the language is prototype-based, the latest JavaScript standard, named ECMAScript 6 (ES6), provides native support for implementing classes. Even though most m...

Finding Classes in Legacy Code Using Cluster Analysis

Old software systems are still in use because they implement useful business tasks. Unfortunately, they are difficult to adapt. They have been subject to maintenance repeatedly, have become less and less comprehensible, and they are closely tied to old technology. To address these problems, much research has been carried out to extract business objects — groups of data and associated operations...

JSZap: Compressing JavaScript Code

JavaScript is widely used in web-based applications, and gigabytes of JavaScript code are transmitted over the Internet every day. Current efforts to compress JavaScript to reduce network delays and server bandwidth requirements rely on syntactic changes to the source code and content encoding using gzip. In this paper, we consider reducing the JavaScript source code to a compressed abstract sy...
