JavaScript is expected to be a programming language of even wider use, considering demands for more interactive web/mobile applications. While reliability of JavaScript code will be of more importance, testing techniques for the language remain insufficient compared to other languages. We propose a technique to automatically generate high-coverage unit tests for JavaScript code. The technique m...

The web is ubiquitous, yet many machine learning algoriths cannot be readily found and applied in JavaScript. An inherent downside to machine learning in JavaScript is lack of speed. However, as the language becomes increasingly more popular, the need for machine learning algorithms steadily rises. First and foremost, JavaScript is the language of the web browser. Having machine learning availa...

As with all untyped languages, JavaScript programs can contain type-mismatch-style errors. These mistakes do not necessarily cause runtime errors and can lead to subtle faults in deployed web apps. Type checking key portions of JavaScript applications can identify these mistakes early. Previous efforts to augment JavaScript with a type system have led to syntax extensions and compulsory type an...

Web Applications have become increasingly popular as they allow developers to use an uniform platform for user interactions. The dynamic programming language JavaScript used in most Web Applications has performance penalties, that have been addressed by traditional optimization techniques. We have found that while the performance gain of such techniques are positive for a set of established ben...

Nowadays, mobile and web based software has been an integral part of our lives. In recent years, there has been an increase in usage of JavaScript libraries in those kind of software. Although these JavaScript libraries fulfill the functions they have promised with respect to the application program interfaces they provide, they are not robust against unexpected inputs. In this study, the param...

Modern web browsers are ubiquitously used by billions of users, connecting them to the world wide web. From the other side, web browsers do not only provide a unified interface for businesses to reach customers, but they also provide a unified interface for malicious actors to reach users. The highly optimized scripting language JavaScript plays an important role in the modern web, as well as f...

As the Internet penetration rate continuously increases and web browsers show a substantial development, the web becomes a more general and ubiquitous application runtime platform, where the programming language on the client side exclusively is JavaScript. This is the reason why recently JavaScript is more often considered as the lingua franca of the web, or, from a different point of view, th...

In this paper, we present js-assess online playground for automatically assessed JavaScript programming exercises. We show how such automatic assessment systems can be implemented on top of JavaScript tools already used by the software industry. Furthermore, we demonstrate how automatically assessed assignments can be easily embedded to any web page without a server, as assessment runs inside t...
