This is a presentation for a workshop on understanding common JavaScript concepts and techniques by actually implementing a bare basic jQuery library of own.
This document provides an overview of Objective-C for Java developers. It discusses that Objective-C is the primary language for developing Mac and iOS apps due to its performance and ability to interface with Cocoa frameworks. It describes Objective-C classes as having interface and implementation definitions separated into .h and .m files. Methods are defined and called by passing messages to objects, with dispatch handled dynamically at runtime. The document also covers creating and working with Objective-C objects by allocating and initializing them.
Constructor is a special member function that initializes objects of a class. Constructors have the same name as the class and do not have a return type. There are two types of constructors: default constructors that take no parameters, and parameterized constructors that allow passing arguments when creating objects. Constructors are automatically called when objects are created to initialize member variables, unlike regular member functions which must be explicitly called.
The document provides an overview of JavaScript core concepts including:
- A brief history of JavaScript originating from LiveScript and becoming ECMAScript.
- Core misunderstandings about JavaScript being object-oriented and prototype-based.
- Key concepts like objects, functions, scope, 'this', arguments, invocation, and closures.
- How functions work with parameters, return values, and different invocation styles.
- Global versus function scope and how closures allow accessing outer function variables.
- Resources for further reading on JavaScript fundamentals.
Converting your JS library to a jQuery pluginthehoagie
The document discusses converting an existing JavaScript library to a jQuery plugin by encapsulating the code within an anonymous function, allowing options to be passed in at initialization, making private functions truly private, and making the selector and initialization customizable per instance rather than hardcoded. It provides an example of converting some sample code to a jQuery plugin following these best practices in under 20 lines of code.
JavaScript has some stunning features like Closures, Prototype etc. which can help to improve the readability and maintainability of the code. However, it is not easy for inexperienced developer to consume and apply those features in day to day coding. The purpose of the presentation ‘Advanced JavaScript’ is to help a reader easily understand the concept and implementation of some advanced JavaScript features.
Great design patterns are reusable, modular expressions of what’s going on in your code. They allow you to communicate to other developers simply by the way you code, in addition to being easily maintainable themselves. Put simply, patterns are the available tools in the developer’s toolbox.
In this presentation, I review a few common patterns, their advantages/disadvantages, and how they can be implemented.

Javascript is a dynamic scripting language used widely for client-side web development. It allows asynchronous HTTP (AJAX) requests to update pages dynamically without reloading. Key features include variables, functions, objects, conditionals, closures and exceptions. The DOM represents the structure of a web page and can be manipulated with Javascript to dynamically change content, add/remove elements.
This document discusses JavaScript inheritance using prototypes. It explains that objects inherit from other objects through their internal __proto__ property. Constructors set an object's __proto__ to reference the constructor's prototype. Methods can be added to the prototype and all objects will inherit those methods. The document also covers how to implement inheritance between constructors like Employee inheriting from Person without calling the parent constructor.
The document provides an overview of object-oriented programming concepts in JavaScript, including:
- JavaScript uses prototype-based inheritance rather than classes, with functions serving as constructors.
- Objects inherit properties and methods from other objects via their prototype chain.
- Custom objects are defined with constructor functions that set properties and methods.
- Inheritance allows creating subclasses that inherit from superclasses. Methods can be overridden.
- Encapsulation involves exposing an object's data through getter/setter methods rather than direct access.
- Superclass members can be accessed in subclasses through calling the superclass constructor or methods.
- Constructor arguments are passed to subclasses by applying the superclass constructor.
Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects. It's the tie to go along with jQuery's tux.
This document provides an overview of Mongoose and how to get started using it with MongoDB. It explains how to connect to a MongoDB database, define a schema for documents, compile a model, create and save documents to the database, add methods to documents, and query the database. Key aspects covered include defining schemas with fields and validators, creating document instances from models, saving documents, adding methods to schemas to expose functionality on documents, and querying for all documents in a collection.
Mongoose is an object data modeling (ODM) library for MongoDB and Node.js which allows for defining schemas and models. It provides features like validation, middleware, population (joins), and document operation methods. With Mongoose, schemas can be defined to specify the structure and types of data, and models can then be created to interact with MongoDB documents according to those schemas.
This document discusses the MongoDB shell, which is a JavaScript interpreter with built-in support for MongoDB. It can be used for interactive development, testing, administration, and learning MongoDB. The shell allows running queries, saving documents, and has features like command completion, history, and helpers for common tasks. While powerful, it has some limitations like performance and lack of modern JavaScript features. Overall, the document recommends using the shell to better understand and work with MongoDB.
The document discusses various web frameworks including Node.js, Express.js, and Django. It provides an introduction to each framework, explaining what they are used for and some of their main features. Node.js is introduced as a framework for running JavaScript on the server and some of its core modules are described. Express.js is presented as a web application framework built on Node.js. Django is introduced as a Python web framework that allows for quick development with minimal code.

A DECISION SUPPORT SYSTEM FOR ESTIMATING COST OF SOFTWARE PROJECTS USING A HY...ijfcstjournal
One of the major challenges for software, nowadays, is software cost estimation. It refers to estimating the
cost of all activities including software development, design, supervision, maintenance and so on. Accurate
cost-estimation of software projects optimizes the internal and external processes, staff works, efforts and
the overheads to be coordinated with one another. In the management software projects, estimation must
be taken into account so that reduces costs, timing and possible risks to avoid project failure. In this paper,
a decision- support system using a combination of multi-layer artificial neural network and decision tree is
proposed to estimate the cost of software projects. In the model included into the proposed system,
normalizing factors, which is vital in evaluating efforts and costs estimation, is carried out using C4.5
decision tree. Moreover, testing and training factors are done by multi-layer artificial neural network and
the most optimal values are allocated to them. The experimental results and evaluations on Dataset
NASA60 show that the proposed system has less amount of the total average relative error compared with
COCOMO model.

2. Whats it about?
Understanding concepts and common
techniques used in JavaScript by implementing
parts of an existing library.
1. Pick a concept
2. Understand the theory.
3. Implement related jQuery code.
4. Back to step 1.
3. What we’ll learn
1. Prototypes: jQuery core
2. Use of ‘this’: jQuery core
3. Implement $.css()
4. A Brief on
jQuery is JavaScript library that provides utility
functions to do:
1. DOM manipulations.
2. Animations.
3. AJAX calls.
“consistently across browser”
5. A Brief on
(contd.)
So you can do things like this:
To remove an element with ID ‘container’
$(‘#container’).remove();
To animate and open the same element
$(‘#container’).slideDown();
6. 1. Prototype: Objects
- Everything in JavaScript is an Object.
- function foo () {}
- var obj = {a: 3} (obviously)
- var arr = [9, 2, 11]
- var str = ‘Just a string’
- Each object inherits Object.
7. Inheritance
This is what inheritance means:
Object myObj = {}
myObj’s prototype is
Object.prototype;
8. Lets create some objects
var obj = Object.create({prop: ‘hello’});
The hidden __proto__ property.
“We code...”
9. Constructor functions -> Classes
var instance = new Foo(obj);
1. Create a new object: o.
2. Set o’s prototype equal to Foo’s prototype.
3. Calls Foo with context as o (we’ll see what it
means).
3. Set it on instance.
10. Our jQuery class
Properties
● selector
● node
$(‘#container’)
should give us an instance of our jQuery class
with `selector` property as #container and
`node` as the actual container object.
“We code...”
11. 2. Use of ‘this’
- `this` in object methods.
- function foo() { return this; }
- foo.apply()
- foo.call()
