Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book offers a detailed explanation of the features that make JavaScript an outstanding object-oriented programming language, and warns you about the bad parts.
In the process, JavaScript: The Good Parts defines a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole. Author Douglas Crockford, a member of JavaScript 2.0 committee at ECMA, is considered by many people in the development community to be the JavaScript expert.
A beautiful, elegant, lightweight and highly expressive language lies buried under a steaming pile of good intentions and blunders, he explains. The very good ideas include functions, loose typing, dynamic objects, and an expressive object literal notation. Awful ideas include a programming model based on global variables. With JavaScript: The Good Parts, you can release this elegant programming language from its old shell, and create more maintainable, extensible, and efficient code.
The book's topics include:
* Syntax
* Objects
* Functions
* Inheritance
* Arrays
* Regular expressions
* Methods
* Style
* Beautiful features
Appendices summarize JavaScript's bad parts and awful parts. But the greatest benefit of studying the good parts is that you can avoid the need to unlearn the bad parts. If you want to learn more about the bad parts and how to use them badly, consult any other JavaScript book.
JavaScript is the language of the Web -- the only language found in all browsers -- so avoiding it altogether is not an alternative. But, whether you're managing object libraries or just trying to get Ajax to run fast, Crockford's guidance in JavaScript: The Good Parts will help you create truly effective JavaScript code.

The Definitive Guide to Java Platform Best Practices—Updated for Java 9
Java has changed dramatically since the previous edition of Effective Java was published shortly after the release of Java 6. This Jolt award-winning classic has now been thoroughly updated to take full advantage of the latest language and library features. The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers.
As in previous editions, each chapter of Effective Java, Third Edition, consists of several “items,” each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why.
The third edition covers language and library features added in Java 7, 8, and 9, including the functional programming constructs that were added to its object-oriented roots. Many new items have been added, including a chapter devoted to lambdas and streams.
New coverage includes
Functional interfaces, lambda expressions, method references, and streams
Default and static methods in interfaces
Type inference, including the diamond operator for generic types
The @SafeVarargs annotation
The try-with-resources statement
New library features such as the Optional<T> interface, java.time, and the convenience factory methods for collections

More and more programmers are turning to Python and this book will give
them the understanding they need. Necaise introduces the basic array
structure and explores the fundamentals of implementing and using
multi-dimensional arrays. The underlying mechanisms of many of Python’s
built-in data structures and constructs are covered. A number of ADTs
and applications are discussed as threads throughout the book to allow
for multiple implementations as new data structures are introduced.
Real-world applications of the various chapter topics are also
presented. This gives programmers complete coverage of abstraction and
the basic data structures and algorithms in the Python language.

"Test-Driven Development with Python" focuses on web development, with some coverage of JavaScript (inescapable for any web programmer).
This book uses a concrete example - the development of a web site, from scratch - to teach the TDD metholology, and how it applies to web programming, from the basics of database integration and javascript, going via browser-automation tools like Selenium, to advanced (and trendy) topics like NoSQL, websockets and Async programming.

More than ever, the web is a universal platform for all types of applications, and JavaScript is the language of the web. For anyone serious about web development, it's not enough to be a decent JavaScript coder. They need to be ninja-stealthy, efficient, and ready for anything.
Secrets of the JavaScript Ninja, Second Edition dives below the surface and helps readers understand the deceptively-complex world of JavaScript and browser-based application development. It skips the basics, and dives into core JavaScript concepts such as functions, closures, objects, prototypes, promises, and so on. With examples, illustrations, and insightful explanations, readers will benefit from the collective wisdom of seasoned experts John Resig, Bear Bibeault, and Josip Maras.
