Learning JavaScript Design Patterns

Design patterns are reusable solutions to commonly occurring problems in software design. They are both exciting and a fascinating topic to explore in any programming language. One reason for this is that they help us build upon the combined experience of many developers that came before us and ensure we structure our code in an optimized way, meeting the needs of problems we're attempting to solve. Design patterns also provide us a common vocabulary to describe solutions. This can be significantly simpler than describing syntax and semantics when we're attempting to convey a way of structuring a solution in code form to others. In this book we will explore applying both classical and modern design patterns to the JavaScript programming language. Target Audience This book is targeted at professional developers wishing to improve their knowledge of design patterns and how they can be applied to the JavaScript programming language. Acknowledgments Credits Reading We already use patterns everyday

Getting started - Polymer Basics The basics of using Polymer are simple: Load platform.js to polyfill missing platform features, such as Shadow DOM and HTML Imports . Load components with <link rel="import" href="/path/to/component-file.html"> Use the custom element in your page. Here’s a bare bones example: For Your Script Loading Needs As JavaScript usage has skyrocketed over the last few years, so has the sheer number of scripts that are being loaded in an average web page. With these script tags comes a lot of baggage, such as blocking and lack of dependency management. Today, I'd like to bring your attention to a number of JavaScript loaders, which are mini toolkits that significantly simplify how you add and load scripts. The Problem with Simple Script Tags

Understanding the four layers of JavaScript OOP JavaScript OOP is baffling: on one hand, there is a simple core, on the other hand, there are some really weird things going on. I’ve been pondering for a long time how to explain it well and I think the best way to do so is via four layers: single objects, prototype chains, constructors, constructor inheritance. The first two layers are JavaScript’s simple OOP core, layers 3 and 4 are where the complications start. I’ve explained the four OOP layers in an O’Reilly webcast: Video on YouTube (starts later to avoid duplicated content at the beginning)SlidesFull webcast (requires Flash, but the audience’s comments in the chat are interesting) Additional material:
