Java Memory Management. A comprehensive guide to garbage collection and JVM tuning

Maaike van Putten, Seán Kennedy

Understanding how Java organizes memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals. Having in-depth knowledge of memory functioning and management is incredibly useful in writing and analyzing code, as well as debugging memory problems. In fact, it can be just the knowledge you need to level up your skills and career.In this book, you’ll start by working through the basics of Java memory. After that, you’ll dive into the different segments individually. You’ll explore the stack, the heap, and the Metaspace. Next, you’ll be ready to delve into JVM standard garbage collectors. The book will also show you how to tune, monitor and profile JVM memory management. Later chapters will guide you on how to avoid and spot memory leaks.By the end of this book, you’ll have understood how Java manages memory and how to customize it for the benefit of your applications.

JavaScript from Beginner to Professional. Learn JavaScript quickly by building fun, interactive, and dynamic web apps, games, and pages

Laurence Lars Svekis, Maaike van Putten, Codestars By Rob Percival

This book demonstrates the capabilities of JavaScript for web application development by combining theoretical learning with code exercises and fun projects that you can challenge yourself with. The guiding principle of the book is to show how straightforward JavaScript techniques can be used to make web apps ranging from dynamic websites to simple browser-based games.JavaScript from Beginner to Professional focuses on key programming concepts and Document Object Model manipulations that are used to solve common problems in professional web applications. These include data validation, manipulating the appearance of web pages, working with asynchronous and concurrent code.The book uses project-based learning to provide context for the theoretical components in a series of code examples that can be used as modules of an application, such as input validators, games, and simple animations. This will be supplemented with a brief crash course on HTML and CSS to illustrate how JavaScript components fit into a complete web application.As you learn the concepts, you can try them in your own editor or browser console to get a solid understanding of how they work and what they do. By the end of this JavaScript book, you will feel confident writing core JavaScript code and be equipped to progress to more advanced libraries, frameworks, and environments such as React, Angular, and Node.js.

JavaScript od pierwszej linii kodu. Błyskawiczna nauka pisania gier, stron WWW i aplikacji internetowych

Laurence Lars Svekis, Maaike van Putten, Rob Percival

JavaScript jest niewielkim językiem skryptowym o imponujących możliwościach. Można w nim tworzyć wiele różnych rodzajów oprogramowania. Doskonale się nadaje do tworzenia dynamicznych stron internetowych, a także do budowy aplikacji internetowych i gier. Mimo upływu lat JavaScript jest niezwykle popularny, a pracę w tym języku ułatwia szereg frameworków, narzędzi i bibliotek. Przyszli zawodowi programiści powinni jednak zacząć naukę od samodzielnego pisania kodu - nawet jeśli na początku wydaje się to trudne. Dzięki temu przyjaznemu przewodnikowi poznasz kluczowe koncepcje programistyczne i operacje obiektowego modelu dokumentu. Nauczysz się też pisać kod działający asynchronicznie i współbieżnie. Poszczególne zagadnienia zostały zilustrowane przykładowymi fragmentami kodu i prostymi projektami ― pozwoli Ci to natychmiast wypróbować działanie tworzonych programów, które w przyszłości mogą posłużyć jako moduły większych aplikacji. Zagadnienia dotyczące JavaScriptu uzupełniono wprowadzeniem do HTML i CSS, co pomoże Ci dokładnie zrozumieć sposób działania nowoczesnych aplikacji internetowych. Przygotujesz się także do pracy z bibliotekami, frameworkami i takimi narzędziami jak React, Angular i Node.js. W książce: konstrukcje logiczne w kodzie źródłowym pętle, funkcje i metody JavaScriptu współdziałanie z HTML5, współbieżność i programowanie asynchroniczne wyrażenia regularne wprowadzenie do najważniejszych bibliotek, frameworków i API JavaScript: proste narzędzie do złożonych zadań!
