Javascript-patterns/object-creation-patterns/sandbox.html at master · shichuan/javascript-patterns. Nicholas Zakas: Scalable JavaScript Application Architecture. Patterns For Large-Scale JavaScript Application Architecture. Today we're going to discuss an effective set of patterns for large-scale JavaScript application architecture.

Patterns For Large-Scale JavaScript Application Architecture

The material is based on my talk of the same name, last presented at LondonJS and inspired by previous work by Nicholas Zakas. Who am I and why am I writing about this topic? I'm currently a JavaScript and UI developer at AOL helping to plan and write the front-end architecture to our next generation of client-facing applications. As these applications are both complex and often require an architecture that is scalable and highly-reusable, it's one of my responsibilities to ensure the patterns used to implement such applications are as sustainable as possible. I also consider myself something of a design pattern enthusiast (although there are far more knowledgeable experts on this topic than I). Can you summarize this article in 140 characters?

jsf - Javascript self contained sandbox events and client side stack

Deeper separation in Module Sandbox Core Javascript Pattern. Following the ideas from Patterns For Large-Scale JavaScript Application Architecture and Nicholas Zakas: Scalable JavaScript Application Architecture I began to implement my college license project using this architecture.

Deeper separation in Module Sandbox Core Javascript Pattern

I have encountered a situation where it is unclear how I should proceed. To illustrate the scenario I will try to give a solid example: I have two modules that are started via the CORE, they are legit modules that get a sandbox instance each. One module displays the dashboard main content of an administration area, and the other one displays the user profile main content of the admin area. Both modules make use of the sandbox to fetch content via Ajax from the server.

This design pattern states that modules should not have any other dependencies apart from the Sandbox. My question is, how would I expose the User Statistics Mini Module to my Dashboard and Profile big Modules? Annotated ES5. Simple JavaScript Inheritance. I’ve been doing a lot of work, lately, with JavaScript inheritance – namely for my work-in-progress JavaScript book – and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques.

Simple JavaScript Inheritance

Out of all the ones that I’ve looked at I think my favorites were the implementations employed by base2 and Prototype. I wanted to go about extracting the soul of these techniques into a simple, re-usable, form that could be easily understood and didn’t have any dependencies. Additionally I wanted the result to be simple and highly usable. Here’s an example of what you can do with it: A couple things to note about this implementation: Creating a constructor had to be simple (in this case simply providing an init method does the trick).In order to create a new ‘class’ you must extend (sub-class) an existing class.All of the ‘classes’ inherit from a single ancestor: Class. 5 Must-Reads on JavaScript Inheritance. By Karthik Viswanathan Do you know inheritance in JavaScript?

5 Must-Reads on JavaScript Inheritance

Do you truly understand how it works? Are you aware that JavaScript uses a prototypal inheritance scheme that is often disfavored or disliked? Have you used a script on the web to adapt this scheme to classical inheritance? In these past few days, I’ve been writing a jQuery slider plugin with various transition effects. Design - How prototypal inheritance is practically different from classical inheritance. Inheritance, Polymorphism, and Encapsulation are the three most distinct, important features of OOP, and from them, inheritance has a high usage statistics these days.

design - How prototypal inheritance is practically different from classical inheritance

I'm learning JavaScript, and here, they all say that it has prototypal inheritance, and people everywhere say that it's something far different from classical inheritance. However, I can't understand what's their difference from the point of practical usage? In other words, when you define a base class (prototype) and then derive some subclasses from it, you both have access to functionalites of your base class, and you can augment functions on the derived classes. If we consider what I said to be the intended result of inheritance, then why should we care if we're using prototypal or classic version? To clear myself more, I see no difference in the usefulness and usage patterns of prototypal and classic inheritance.

Classical Inheritance in JavaScript. Douglas Crockford And you think you're so clever and classless and free — John Lennon JavaScript is a class-free, object-oriented language, and as such, it uses prototypal inheritance instead of classical inheritance.

Classical Inheritance in JavaScript

This can be puzzling to programmers trained in conventional object-oriented languages like C++ and Java. JavaScript's prototypal inheritance has more expressive power than classical inheritance, as we will see presently. But first, why do we care about inheritance at all? The second reason is code reuse. To demonstrate this, we will introduce a little sugar which will let us write in a style that resembles a conventional classical language. Classical Inheritance First, we will make a Parenizor class that will have set and get methods for its value, and a toString method that will wrap the value in parens. The syntax is a little unusual, but it is easy to recognize the classical pattern in it. So now we can write As you would expect, myString is "(0)". Sugar. What ASP.NET Developers Should Know About JavaScript. JavaScript – It's beat up, put down, shrugged off and kicked around.

What ASP.NET Developers Should Know About JavaScript

Cursed by the web browser's inconsistency yet blessed by a pervasive ubiquity -it's a technology many try to disregard even when its potential is something few can ignore. If you want to write an interactive application for the web today, then you'll need some JavaScript code on your side. Prototypes and Inheritance in JavaScript. Forget everything you know about object-oriented programming.

Prototypes and Inheritance in JavaScript

Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. Manufacturers put an enormous amount of money into researching, engineering, and building these prototype cars, and the engineers are always trying to find an edge. You could say mainstream cars inherit technology from racing prototypes.
