A study of causes and consequences of client-side JavaScript bugs

摘要

JavaScript and web applications are very important aspects of the software products developed for both browser-and mobile-based applications. One pillar of such application development is the usage of JavaScript for interaction with clients (for example, the browser or the mobile device). Unfortunately, JavaScript is an error-prone language, and it is hard to debug, mostly due to the lack of tools helping both coders and testers. In particular, JavaScript bugs are subtle: They can either produce an error message or not (the code continues to be executed after the failure, without any message notice).
