AngularJS — Superheroic JavaScript MVW Framework Chapter 17. Objects and Inheritance Chapter 17. Objects and Inheritance There are several layers to object-oriented programming (OOP) in JavaScript: Each new layer only depends on prior ones, enabling you to learn JavaScript OOP incrementally. Roughly, all objects in JavaScript are maps (dictionaries) from strings to values. There are three kinds of properties: Properties (or named data properties) Normal properties in an object—that is, mappings from string keys to values. Accessors (or named accessor properties) Special methods whose invocations look like reading or writing properties. Internal properties Exist only in the ECMAScript language specification.

This resource originally created by Deborah Dunk. Home » OpenStack Open Source Cloud Computing Software Learning JavaScript Design Patterns I would like to thank Rebecca Murphey for inspiring me to open-source this mini-book and release it for free download and distribution - making knowledge both open and easily available is something we should all strive for where possible. I would also like to extend my thanks to the very talented Alex Sexton who was kind enough to be the technical reviewer for this publication. I hope that it helps you learn more about design patterns and the usefulness of their application to JavaScript. Volume 2 of Essential JavaScript Design Patterns is currently being written and will be more detailed than this first edition. The ETA for it's online release is late Q4, 2011. For more detailed coverage of specific patterns, you may be interested in my posts on the Pub/Sub (Observer) or Decorator patterns. At the beginning of this book I will be focusing on a discussion about the importance and history of design patterns in any programming language. Patterns are not an exact solution.

Understanding Design Patterns in JavaScript Today, we're going to put on our computer science hats as we learn about some common design patterns. Design patterns offer developers ways to solve technical problems in a reusable and elegant way. Interested in becoming a better JavaScript developer? Then read on. Republished Tutorial Every few weeks, we revisit some of our reader's favorite posts from throughout the history of the site. Solid design patterns are the basic building block for maintainable software applications. A design pattern is a reusable software solution Simply put, a design pattern is a reusable software solution to a specific type of problem that occurs frequently when developing software. patterns are proven solutions to software development problems patterns are scalable as they usually are structured and have rules that you should follow patterns are reusable for similar problems We'll get into some examples of design patterns further in to the tutorial. Take a look at the three examples above.

The Big Android Dictionary: A Glossary of Terms You Should Know The Big Android Dictionary: A Glossary of Terms You Should Know Android comprises an entire ecosystem of apps, games, functions, and features, so it would only make sense that it has its own lexicon. Words, phrases, and acronyms that didn't exist 7 years ago are now used in an off-the-cuff style by developers and support technicians across the web. As the platform matures, this list of unique Android words continues to evolve, which makes it hard to stay on top of the latest terminology. But breaking things down into simple terms is what we do best here at Gadget Hacks, so below, we'll cover all of the latest Android lingo in layman's terms. Hint: If you're looking to define a specific term, use the "Find" function in your browser (Ctrl + F or Command + F) to jump right to it.
