It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL). -

Javascript API Deprecation in the Wild: a First Assessment
JavaScript API Deprecation in the Wild: A First Assessment Romulo Nascimento, Aline Brito, Andre Hora, Eduardo Figueiredo Department of Computer Science Federal University of Minas Gerais, Brazil romulonascimento, alinebrito, andrehora,figueiredo @dcc.ufmg.br { } Abstract—Building an application using third-party libraries of our knowledge, there are no detailed studies regarding API is a common practice in software development. As any other deprecation in the JavaScript ecosystem. software system, code libraries and their APIs evolve over JavaScript has become extremely popular over the last years. time. In order to help version migration and ensure backward According to the Stack Overflow 2019 Developer Survey1, compatibility, a recommended practice during development is to deprecate API. Although studies have been conducted to JavaScript is the most popular programming language in this investigate deprecation in some programming languages, such as platform for the seventh consecutive year. GitHub also reports Java and C#, there are no detailed studies on API deprecation that JavaScript is the most popular language in terms of unique in the JavaScript ecosystem. This paper provides an initial contributors to both public and private repositories2. The npm assessment of API deprecation in JavaScript by analyzing 50 platform, the largest JavaScript package manager, states on popular software projects. Initial results suggest that the use of 3 deprecation mechanisms in JavaScript packages is low. However, their latest survey that 99% of JavaScript developers rely on wefindfive different ways that developers use to deprecate API npm to ease the management of their project dependencies. in the studied projects. Among these solutions, deprecation utility This survey also points out the massive growth in npm usage (i.e., any sort of function specially written to aid deprecation) and that started about 5 years ago. -

Introducing 2D Game Engine Development with Javascript
CHAPTER 1 Introducing 2D Game Engine Development with JavaScript Video games are complex, interactive, multimedia software systems. These systems must, in real time, process player input, simulate the interactions of semi-autonomous objects, and generate high-fidelity graphics and audio outputs, all while trying to engage the players. Attempts at building video games can quickly be overwhelmed by the need to be well versed in software development as well as in how to create appealing player experiences. The first challenge can be alleviated with a software library, or game engine, that contains a coherent collection of utilities and objects designed specifically for developing video games. The player engagement goal is typically achieved through careful gameplay design and fine-tuning throughout the video game development process. This book is about the design and development of a game engine; it will focus on implementing and hiding the mundane operations and supporting complex simulations. Through the projects in this book, you will build a practical game engine for developing video games that are accessible across the Internet. A game engine relieves the game developers from simple routine tasks such as decoding specific key presses on the keyboard, designing complex algorithms for common operations such as mimicking shadows in a 2D world, and understanding nuances in implementations such as enforcing accuracy tolerance of a physics simulation. Commercial and well-established game engines such as Unity, Unreal Engine, and Panda3D present their systems through a graphical user interface (GUI). Not only does the friendly GUI simplify some of the tedious processes of game design such as creating and placing objects in a level, but more importantly, it ensures that these game engines are accessible to creative designers with diverse backgrounds who may find software development specifics distracting. -

Object Query Language Reference Version: Itop 1.0
Object Query Language Reference Version: Itop 1.0 Overview OQL aims at defining a subset of the data in a natural language, while hiding the complexity of the data model and benefit of the power of the object model (encapsulation, inheritance). Its syntax sticks to the syntax of SQL, and its grammar is a subset of SQL. As of now, only SELECT statements have been implemented. Such a statement do return objects of the expected class. The result will be used by programmatic means (to develop an API like ITOp). A famous example: the library Starter SELECT Book Do return any book existing in the Database. No need to specify the expected columns as we would do in a SQL SELECT clause: OQL do return plain objects. Join classes together I would like to list all books written by someone whose name starts with `Camus' SELECT Book JOIN Artist ON Book.written_by = Artist.id WHERE Artist.name LIKE 'Camus%' Note that there is no need to specify wether the JOIN is an INNER JOIN, or LEFT JOIN. This is well-known in the data model. The OQL engine will in turn create a SQL queries based on the relevant option, but we do not want to care about it, do we? © Combodo 2010 1 Now, you may consider that the name of the author of a book is of importance.

Teaching Introductory Programming with Javascript in Higher Education
Proceedings of the 9th International Conference on Applied Informatics Eger, Hungary, January 29–February 1, 2014. Vol. 1. pp. 339–350 doi: 10.14794/ICAI.9.2014.1.339 Teaching introductory programming with JavaScript in higher education Győző Horváth, László Menyhárt Department of Media & Educational Informatics, Eötvös Loránd University, Budapest, Hungary [email protected] [email protected] Abstract As the Internet penetration rate continuously increases and web browsers show a substantial development, the web becomes a more general and ubiq- uitous 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, the universal virtual machine of the web. In ad- dition, the JavaScript programming language appears in many other areas of informatics due to the wider usage of the HTML-based technology, and the embedded nature of the language. Consequently, in these days it is quite difficult to program without getting in touch with JavaScript in some way. In this article we are looking for answers to how the JavaScript language is suitable for being an introductory language in the programming related subjects of the higher education. First we revisit the different technologies that lead to and ensure the popularity of JavaScript. Following, current approaches using JavaScript as an introductory language are overviewed and analyzed. Next, a curriculum of an introductory programming course at the Eötvös Loránd University is presented, and a detailed investigation is given about how the JavaScript language would fit in the expectations and requirements of this programming course. -
