JavaScript is the behavior, the third pillar in today's paradigm that looks at web pages as something that consists of clearly distinguishable parts: content (HTML), presentation (CSS) and behavior (JavaScript). Using JavaScript, you can create not only web pages but also desktop widgets, browser and application extensions, and other pieces of software. It's a pretty good deal: you learn one language and then code all kinds of different applications. While there's one chapter specifically dedicated to the web browser environment including DOM, Events and AJAX tutorials, the rest is applicable to the other environmentsMany web developers have tried coding or adopting some bits of JavaScript, but it is time to man up and learn the language properly because it is the language of the browser and is, virtually, everywhere. This book starts from zero, not assuming any prior JavaScript programming knowledge and takes you through all the in-depth and exciting futures hidden behind the facade. Once listed in the nice to have sections of job postings, these days the knowledge of JavaScript is a deciding factor when it comes to hiring web developers. After reading this book you'll be prepared to ace your JavaScript job interview and even impress with some bits that the interviewer maybe didn't know. You should read this book if you want to be able to take your JavaScript skills to a new level of sophistication.

Object-Oriented Programming is a textbook that will enable any reader, regardless of their level, to understand the basic principles of structured and object-oriented programming. A beginner will have the opportunity to learn almost from scratch, and an advanced programmer will be able to consolidate, practice, and significantly expand his or her knowledge. In the book, the author has gathered a large amount of basic programming concepts, explaining the concept of data, its types and more complex structures, i.e. collections, along with the ways of referring to them through names and pointers. He discussed conditional statements, iteration, functions, objects and classes, as well as inheritance, polymorphism and access rules. An additional advantage of the content discussed is the questions and exercises with answers and the source codes of all programs with the possibility of downloading them directly to the computer. The author of the book is Aleksander Bies, a teacher of programming, a graduate of Computer Science and Applied Computer Science at the Faculty of Science and Technology of the University of Silesia, a doctoral candidate in the field of artificial intelligence methods in complex systems. He is the co-author of a machine learning model that won 2nd place in the international Orange Datahack with Energy competition.

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects; these are data structures that contain data in the form of fields, often known as attributes and code. Objects are everywhere, and so it is very important to recognize elements, known as objects, from real-world situations and know how they can easily be translated into object-oriented code.Object-Oriented Programming with Swift is an easy-to-follow guide packed full of hands-on examples of solutions to common problems encountered with object-oriented code in Swift. It starts by helping you to recognize objects using real-life scenarios and demonstrates how working with them makes it simpler to write code that is easy to understand and reuse. You will learn to protect and hide data with the data encapsulation features of Swift. Then, you will explore how to maximize code reuse by writing code capable of working with objects of different types. After that, you'll discover the power of parametric polymorphism and will combine generic code with inheritance and multiple inheritance. Later, you move on to refactoring your existing code and organizing your source for easy maintenance and extensions.By the end of the book, you will be able to create better, stronger, and more reusable code, which will help you build better applications.

When building mobile apps, it’s easy to forget about the moments when your users lack a good Internet connection. Put your phone in airplane mode, open a few popular apps, and you’ll quickly see how they handle being offline. From Twitter to Pinterest to Apple Maps, some apps might handle being offline better—but very few do it well. A poor offline experience will result in frustrated users who will abandon your app, or worse, turn to your competitor’s appsExpert or novice, this book will teach you everything you need to know about designing and building a rigorous offline app experience. By putting the offline experience first, you’ll have a solid foundation to build upon, avoiding the unnecessary stress and frustration of trying to retrofit offline capabilities into your finished app. This basic principle, designing for the worst-case scenario, could save you countless hours of wasted effort.
