Title Essential JavaScript and JQuery Design Patterns; Author(s) Addy Osmani eBook Online, HTML, PDF; Language: English; ISBN N/A; ISBN N/A Before we begin, let's look at the exact definition of a 'pattern' in software design. Essential JavaScript And jQuery Design Patterns - A Free New Book The latter is a lot more visually pleasing than the PDF/eBooks I used to like to thank JavaScript and design pattern enthusiast Alex Sexton for technically.

All of these categories are included in this course. Here's a rundown of each category:. Modern Patterns are the more recently 'discovered' patterns. They are among the most frequently used patterns by the JavaScript pros. Just open any popular open-source library or framework and you'll find them used throughout. As a budding JavaScript professional you must be familiar with these. Let's review a great example.

Essential JavaScript And jQuery Design Patterns - A Free New Book

It is a template that is a combination of two Modern patterns: Namespace and Revealing Module. Many of the course's sample apps use this template. Don't worry if the following description is not clear. The course will take you step-by-step through the individual parts.

But here it goes:. What you see is an immediate function with a private area and a public area. The immediate function is the Module Pattern and the public area is the Revealing part.

The private area is for private variables and methods which are hidden by the module. The public area is where you place variables and methods that you wish to expose to the outside world. The Module is assigned to a property, called module , on the MyApp.

Events namespace. This is an implementation of the Namespace Pattern. The namespace method is used to build nested namespaces. These nested namespaces will help prevent name collisions making your apps easier to maintain and very robust.

Applying just these 2 pattern will significantly improve the quality your apps. And we haven't even mentioned the other dozen or so Modern Patterns in this section The Classic Patterns are the 'seniors' among the patterns. They have been around for a while but are still going strong. You will learn which ones are relevant to JavaScript and which ones less so. Not coincidentally, our implementation uses the aforementioned template with Namespace and Revealing Module patterns.

You will notice the template we discussed earlier in this code. Recall that it has a private area and a public area the comments in the code show where each is. It has four function objects: Bank , Credit , Background and Mortgage. They all reside in the private area and are hidden. However, the last one, Mortgage , is exposed by the return statement the public area and the Revealing part of Module. Very elegant and solid code.

The hidden subsystems in this example are Bank , Credit , and Background , The client only requires access to Mortgage which is indeed how it is used in the run function. Again, it is these kinds of solutions that transform JavaScript from being a somewhat limited language to one that is fun and powerful to work with!

Model View MV Patterns are all the rage today. There is good reason for this because they bring structure and organization to your projects. Many big name web sites use Model View Frameworks, such as, groupon. The MV Patterns are a family of three related patterns: This diagram shows the main structure of each one. The course will teach you, step-by-step, the essentials of each of these important patterns.

Upon completion you will have the skills necessary to select the best MV model and framework for your own work and start building MV based apps right away. You will also get a fully functional MVVM shopping cart. It is snappy and works beautifully! Feel free to copy the code and use it in your own projects. The Architectural Patterns work on a higher, architectural level.

You will learn about AMD and its implementation in Require. In fact, AMD is fairly hard to grasp initially, but it is important that you are aware of what it offers and its benefits. Other topics in this section include Error Handling, Testing, and Transpilers. Here's a quick review of each of these.

All JavaScript apps require a dependable approach towards error handling and error logging. This course will introduce you to the error flow in JavaScript as depicted below:. The error flow itself is easy to understand, but it is crucial that your projects follow a solid, consistent approach to handling and logging errors.

This course emphasizes the role of error logging -- from the client to the server -- because without it you have no idea about the errors on the browser: In this course you will learn about testing using two popular testing libraries: QUnit and Jasmine.

We will explore JavaScript test cases and test suites with plenty of examples. Perhaps you have worked with any of these languages: What they have in common is that at compile-time their code gets translated to standard JavaScript. These source-to-source compilers are called transpilers i. Once compiled the JavaScript runs on any browser. Of these four languages TypeScript is particularly interesting because it translates a future version of JavaScript to today's version of JavaScript.

TypeScript is designed with an eye toward future versions of JavaScript. Exploring the translated TypeScript code i. This as a huge validation for all the patterns currently in use by the JavaScript community because many were designed to implement features that are missing from JavaScript but that are common in mature, object-oriented languages.

If nothing else, TypeScript offers a great educational value for those interested in JavaScript patterns. Lucky for us, the Typescript website typescriptlang. Here are some examples of before code TypeScript on the left and after code JavaScript on the right:. In this we are checking how a TypeScript class is translated to JavaScript:. The TypeScript class is translated to a JavaScript Module pattern implementation no worries if you don't understand; you will learn about this in the course.

The constructor on the left is implemented as a nested function on the right. It has the same name as the surrounding function i.

The new Person both left and right will create a new Person instance. In the next example we are checking how a TypeScript module is translated to JavaScript:. The TypeScript module on the left is implemented as a simple global variable var MyApp on the right. The Module pattern is used to attach export classes to the module.

As in the first example, the classes themselves are implemented using the Module pattern. This allows the module definition to be spread over multiple files which is great for team development. Multi-file modules are explained in the course. In the final example we are checking how TypeScript class inheritance is translated to JavaScript:.

On the left is an Employee class that extends derives from a Person class. The right-hand side appears complex with all the underscores. However, please be assured that that once you are familiar with the materials in the course everything will fall into place! Your familiarity with patterns will allow you to fully understand what is happening in the translated code.

The Person and Employee classes are implemented using the Module pattern which is built with immediate functions in JavaScript. The constructors are nested functions by the same name as their parent functions.

Again, don't let this code scare you; with the help of this course you'll be able to read and write advanced JavaScript programs like a pro. Upon completion you will confidently and comfortably read code like that on the right hand side. In fact, your own code will probably look quite similar -- but without all the messy code-generated underscores we hope: The pattern guide comes with a comprehensive section on jQuery patterns.

Understanding jQuery patterns is important because it will allow you to make optimal use of this powerful library. Furthermore, it never hurts to study code created by the best JavaScript developers around. The jQuery authors have used patterns extensively to build this amazing library. You'll find patterns throughout their code base 10, lines of code.

Examples of jQuery patterns include: The authors also use several of the classic GoF patterns: JavaScript does not natively support function overloading. Don't worry if you are not familiar with overloading: Essentially it allows you to have multiple functions with the same name, but each with a different set of parameters.

It uses a technique called argument switching , the details of which are explained in the course.

It behaves differently depending on the arguments provided. This goes beyond regular function overloading and could be called semantic overloading. Don't worry if you don't quite understand some of this; all the details are in the course.

Another widely used pattern in jQuery is the Chaining pattern. Chaining allows method calls to be strung together in a single statement, like so:. Some jQuery developers don't know that chaining can also be applied to events, like so:. Not only reduces it the code size, it also makes a huge difference in terms of jQuery performance.

Most methods in jQuery implement the Chaining pattern which allows them be chained with other methods. In your own work, you should consider doing the same; it will make your API more flexible and more usable.

This course will teach you what you need to do to make your methods chainable. This guide also includes jQuery Plugin patterns.

These are proven templates for successful Plugin development which makes writing jQuery custom code a breeze. A common misconception is that Plugins are for open-source projects only. You will discover that Plugins can be very useful also in your own work. This section is the grand finale of the course: They are referred to as: Patterns in Action.

Books and tutorials on JavaScript patterns don't usually show you how to optimally apply these patterns in a real-world environment. This is what makes this course so unique: What makes the sample apps even 'more real-world' is that they include several 3rd party libraries, including jQuery, Backbone, Underscore, and Require. In your own work, you will most likely also use jQuery, a Model View framework, and possibly some other libraries as well.

You are probably wondering what patterns are involved in these apps. Quite a list Note that we didn't set out to cram as many patterns as possible in just lines of JavaScript code. It reflects reality which is that patterns are omnipresent in programs written by professional JavaScript developers. These are great apps to learn from -- and then apply their techniques to your own work! This course offers a unique opportunity to learn to build JavaScript apps like a pro and gain a competitive advantage, which you can build upon every day.

But it takes action. The sooner you learn the patterns and techniques in this course — and apply them — the sooner you will start to see amazing results.

It will teach you how to apply design patterns, best practices, and other advanced techniques to build stunning web apps that are robust, elegant, and maintainable.

I can see you thinking: "Me? I know how to read JavaScript. It is just a scripting language Before hitting the Run button, can you predict the outcome is of this test? First, they short-circuit evaluations, and secondly they return the last evaluated value not necessarily true or false.

The details are provided in the guide. Next, look at this. What do you think will happen? The if-condition passes, but it is neither true nor false. In this course we will get into 'truthy' and 'falsy' values. Now, here's another scenario Suppose you are tasked with correcting a JavaScript web app for a large travel agency.

What others are saying

It was originally written by a JavaScript contractor but he has moved on. The project manager tells you he was a true JavaScript rockstar. By the comments it seems you encountered quite a few WTF moments As a developer you are probabaly wondering: "What's going on and how am I going to deal with this? But there is a more fundamental question: "is this quality code? It is this kind of JavaScript code, filled with idioms hacks and patterns, that you will increasingly encounter as more and more JavaScript developers embrace and apply these generally accepted best practice techniques.

And you sure wouldn't want to be left behind, right? To complete the above task requires that you understand each WTF statement, that is, you need to know 1 what it does, and then 2 why it is used.

If not, how else could you possible participate in and contribute to a professional JavaScript project? Again, this is what this course will provide you: the knowledge and skills necessary to confidently maintain the above module and others like it. The JavaScript you write will be effective, robust, and easy to maintain. In fact, this course may launch your career to whole new path.

Get your copy and start reading and writing JavaScript code like a pro! Are you ready to be a JavaScript pro? As a JavaScript developer it is essential that you fully understand prototypes because it is fundamental to object creation and inheritance. Let me ask you a question: "Each JavaScript object has a prototype, right? All objects have prototypes! The first alert shows an object.

But notice the last alert? It returns 'undefined'. Did I hear WTF? So, why is there no prototype? There is nothing special about the john object instance This course will answer this question and many more, by asking you to forget everything you knew about prototypes.

It will then take you, step by step, through everything you need to know about prototypes. We believe it is the best discussion of prototypes you'll find anywhere. You can search far and wide but nothing will even come close. Here is one of the diagrams we use. Looks complicated, but the course makes it simple: This guide is a great value. And we haven't even mentioned patterns yet. Why not order now? Are you ready?

Take the next step. Get Instant Access Patterns, Patterns, and more Patterns If you browse through the source code of any popular JavaScript library you'll discover it is inundated with design patterns.

Without exception, the authors are also skilled pattern craftsmen. These experts live the JavaScript pattern lifestyle! And so can you, because this course covers all popular JavaScript patterns in use today.

This guide will help you join the ranks of the JavaScript rock stars and enjoy the JavaScript pattern lifestyle. Here's a rundown of each category: Modern Patterns Modern Patterns are the more recently 'discovered' patterns. They are among the most frequently used patterns by the JavaScript pros.

Let's review a great example. It is a template that is a combination of two Modern patterns: Namespace and Revealing Module. Many of the course's sample apps use this template. Here is some skeleton code: MyApp. The course will take you step-by-step through the individual parts.

But here it goes: What you see is an immediate function with a private area and a public area. The immediate function is the Module Pattern and the public area is the Revealing part.

The private area is for private variables and methods which are hidden by the module. The public area is where you place variables and methods that you wish to expose to the outside world. The Module is assigned to a property, called module, on the MyApp.

Not coincidentally, our implementation uses the aforementioned template with Namespace and Revealing Module patterns. Here is the code: Patterns.If not, how else could you possible participate in and contribute to a professional JavaScript project? Perhaps you have a basic understanding of JavaScript and looking at those beautiful large scale sites you're wondering: Spark is an exciting new addition to this package.

To this end, this package comes with 2 comprehensive applications: they are called Patterns in Action 4. This course offers a unique opportunity to learn to build JavaScript apps like a pro and gain a competitive advantage, which you can build upon every day.

I know how to read JavaScript. There is good reason for this because they bring structure and organization to your projects. Axel has done a wonderful job in explaining the complex concept in an easy way. But there is a more fundamental question:
