Essential JavaScript Design Patterns For Beginners

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

JavaScript Scoping and Hoisting Do you know what value will be alerted if the following is executed as a JavaScript program? var foo = 1; function bar() { if (!foo) { var foo = 10; } alert(foo); } bar(); If it surprises you that the answer is “10”, then this one will probably really throw you for a loop: var a = 1; function b() { a = 10; return; function a() {} } b(); alert(a); Here, of course, the browser will alert “1”.

How Do You Structure JavaScript? The Module Pattern Edition JavaScript is interesting in that it enforces no particular structure upon you. "Bring Your Own Organization", if you will. As I write more and more JavaScript in web app sites, this becomes more and more interesting. How you structure your JavaScript is very important because: Done right, it makes code easier to understand for others and yourself re-visting your own code.Having a decided-upon structure helps keep future code clean and encourages your declared best practices.It makes your code testable. Before I go any further, let it be known that I am far from a master of JavaScript.

Quake 3 Source Code Review: Architecture June 30, 2012 Since I had one week before my next contract I decided to finish my "cycle of id". After Doom, Doom Iphone, Quake1, Quake2, Wolfenstein iPhone and Doom3 I decided to read the last codebase I did not review yet: idTech3 the 3D engine that powers Quake III and Quake Live. The engine is mostly an evolution of idTech2 but there are some interesting novelties. ImageMapster ImageMapster is a jQuery plugin that lets you activate HTML image maps without using Flash. It works just about everywhere that Javascript does, including modern browsers, Internet Explorer 6, and mobile devices like iPads, iPhones and Androids. Note: ImageMapster used to be distributed as a ZIP archive. How to learn Javascript and HTML for devs coming from C++/Java/Python? Read Zeldman's "Designing w/ Web Standards, 3rd Edition". That book will give you direction and save you a lot of time. The problem with HTML is that it is a pretty loose language and you can do a lot with it without getting your syntax right. On top of that you have a lot of confusion because of HTML 4.01, HTML5 and XHTML 1.0. Because of all that you will find tons of HTML resources all over the web that may appear decent, but actually teach you bad habits and old hacks that are no longer best practice. Zeldman's book will give you some direction so you don't waste too much time and develop good habits from the beginning.

Everything’s Gone JavaScript « Eric Elliott – JavaScript Architect (A JavaScript Blog) How much of this did you see coming? “Everything that can be written in JavaScript will eventually be written in JavaScript”. – Atwood’s law JavaScript is now an integral part of several operating systems: Tons of mobile apps are either just HTML web views, or use a lot of web views, so a lot of the software that runs on every smartphone is written in JavaScript. JavaScript is also moving quickly into the hardware world: So maybe in the near future, it’ll be in your car, in your GPS, in your toys, your watches, your wearable electronics, and just about everything else you can imagine. Is it time to drop jQuery? Essentials to learning JavaScript from a jQuery background jQuery has been a godsend to pretty much all of us front-end developers since it's release, it's intuitive methods, easy functions make light work of JavaScript's loosely typed language. JavaScript is hard, it's hard to get into, it's much harder than jQuery. But the time is nearly here, going native is going to be the future of front-end - HTML5. HTML5 doesn't just mean a few extra HTML elements, if you're putting down on your CV/Resume that you know HTML5 because you've used the new elements, then think again!
