Performance Optimization and JavaScript Best PracticesDoris Chen
Performance optimization and JavaScript best practices tips are discussed in the talk. Here are some of the tips:
Put stylesheets at the top (css)
Move scripts to the bottom (javascript)
Provide a clean separation of content, CSS, and JavaScript
De-reference unused objects
Think Asynchronous
Working with Objects
Defer Loading Resources
Use JSLint -- Code Quality Tool
Reduce the size of JavaScript file
gzip
General JavaScript Coding Best Practices
Use === Instead of ==
Eval = Bad
Don’t Use Short-Hand
Reduce Globals: Namespace
Don't Pass a String to "SetInterval" or "SetTimeOut"
Use {} Instead of New Object()
Use [] Instead of New Array()
In JavaScript, almost "everything" is an object.
-Booleans can be objects (if defined with the new keyword)
-Numbers can be objects (if defined with the new keyword)
-Strings can be objects (if defined with the new keyword)
-Dates are always objects
-Maths are always objects
-Regular expressions are always objects
-Arrays are always objects
-Functions are always objects
-Objects are always objects

Writing JavaScript as a hobby and writing JavaScript as a job are two very different things. Learn some common practices for making your JavaScript friendly to a team environment.
As a guest speaker in NCU, I gave a talk about some best practices of JavaScript programming to college students. It covers basic JavaScript elements and some common pitfalls while dealing with asynchronous programming.
This presentation will give you a brief background to JavaScript, what it is and where it comes from. Then it will walk you through general pitfalls, best practices and more advanced topics such as object-orientation, scope and closures.
jQuery Selectors
jQuery selectors allow you to select and manipulate HTML element(s).
jQuery selectors are used to "find" (or select) HTML elements based on their name, id, classes, types, attributes, values of attributes and much more. It's based on the existing CSS Selectors, and in addition, it has some own custom selectors.
All selectors in jQuery start with the dollar sign and parentheses: $().
What are Events?
All the different visitors' actions that a web page can respond to are called events.
An event represents the precise moment when something happens.
Examples:
moving a mouse over an element
selecting a radio button
clicking on an element
The term "fires/fired" is often used with events. Example: "The keypress event is fired, the moment you press a key".
JavaScript basics
JavaScript event loop
Ajax and promises
DOM interaction
JavaScript object orientation

In this session, Aaron Gustafson introduces attendees to the client-side scripting language known as JavaScript. After being taken on a quick tour through the language's features and syntax, attendees will be introduced through a series of examples to ways in which JavaScript can progressively enhance the user experience and really make their designs sing. This session also introduces attendees to several JavaScript libraries and demonstrate how to execute the same task in each.
Love it or hate it, JavaScript is playing an increasingly important role in the next generation of web and mobile apps. As code continues to move from the server to the client, JavaScript is being used to do more than simple HTML manipulation. Be prepared for this transition and make sure the JavaScript you write is optimized and ready to perform on desktops and devices! In this session, you will learn ten practical tips that you can use today to write faster, more maintainable, memory friendly JavaScript.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. Object-Oriented JavaScript
// The constructor for our 'Lecture'
// Takes two strings, name and teacher
function Lecture( name, teacher ) {
// Save them as local properties of the object
this.name = name;
this.teacher = teacher;
}
// A method of the Lecture class, used to generate
// a string that can be used to display Lecture information
Lecture.prototype.display = function(){
return this.teacher + quot; is teaching quot; + this.name;
};
// A Schedule constructor that takes in an
// array of lectures
// A method for constructing a string representing
function Schedule( lectures ) {
// a Schedule of Lectures
this.lectures = lectures;
Schedule.prototype.display = function(){
}
var str = quot;quot;;
// Go through each of the lectures, building up
// a string of information
for ( var i = 0; i < this.lectures.length; i++ )
str += this.lectures[i].display() + quot; quot;;
return str;
};
3. Using the Class
// Create a new Schedule object and save it in
// the variable 'mySchedule'
var mySchedule = new Schedule([
// Create an array of the Lecture objects, which
// are passed in as the only argument to the Lecture object
new Lecture( quot;Gymquot;, quot;Mr. Smithquot; ),
new Lecture( quot;Mathquot;, quot;Mrs. Jonesquot; ),
new Lecture( quot;Englishquot;, quot;TBDquot; )
]);
// Display the Schedule information as a pop-up alert
alert( mySchedule.display() );
5. Packaging for Distribution
• Use namespace to avoid conflict with
other library
– For example : public interface library
developed by Yahoo
// Add a mouseover event listener to the element that has an
// ID of 'body'
YAHOO.util.Event.addListener('body','mouseover',function(){
// and change the background color of the element to red
this.style.backgroundColor = 'red';
});
6. Unobtrusive DOM Scripting
• Writing unobtrusive code implies a
complete separation of your HTML
content: the data coming from the
server, and the JavaScript code used
to make it all dynamic
• Writing modern, unobtrusive code
consists of two aspects : the
Document Object Model (DOM), and
JavaScript events
7. The Document Object Model
• The DOM was constructed to provide
an intuitive way for developers to
navigate an XML hierarchy (remember
: valid HTML is simply a subset of
XML)
• Next : Using DOM to Locate and
Manipulate Different DOM Elements
8. <html>
<head>
<title>Introduction to the DOM</title>
<script>
// We can't manipulate the DOM until the document
// is fully loaded
window.onload = function(){
// Find all the <li> elements in the document
var li = document.getElementsByTagName('li');
// and add a ared border around all of them
for ( var j = 0; j < li.length; j++ ) {
li[j].style.border = '1px solid #000';
}
// Locate the element with an ID of 'everywhere'
var every = document.getElementById( quot;everywherequot; );
// and remove it from the document
every.parentNode.removeChild( every );
};
</script>
</head>
<body>
<h1>Introduction to the DOM</h1>
<p class=quot;testquot;>There are a number of reasons why the DOM is awesome, here are some:</p>
<ul>
<li id=quot;everywherequot;>It can be found everywhere.</li>
<li class=quot;testquot;>It's easy to use.</li>
<li class=quot;testquot;>It can help you to find what you want, really quickly.</li>
</ul>
</body>
</html>
9. Events
• Events are the glue that holds together all
user interaction within an application
• JavaScript events are complex and diverse
10. <html>
<head>
<title>Introduction to the DOM</title>
<script>
// We can't manipulate the DOM until the document
// is fully loaded
window.onload = function(){
// Find all the <li> elements, to attach the event handlers to them
var li = document.getElementsByTagName('li');
for ( var i = 0; i < li.length; i++ ) {
// Attach a mouseover event handler to the <li> element,
// which changes the <li>s background to blue.
li[i].onmouseover = function() {
this.style.backgroundColor = 'blue';
};
// Attach a mouseout event handler to the <li> element
// which changes the <li>s background back to its default white
li[i].onmouseout = function() {
this.style.backgroundColor = 'white';
};
}
};
</script>
</head>
<body>
<h1>Introduction to the DOM</h1>
<p class='test'>There are a number of reasons why the DOM is awesome, here are some:</p>
<ul>
<li id='everywhere'>It can be found everywhere.</li>
<li class='test'>It's easy to use.</li>
<li class='test'>It can help you to find what you want, really quickly.</li>
</ul>
</body>
</html>
11. JavaScript and CSS
Cascading style sheets (CSS) serve as the standard for
laying out simple, unobtrusive web pages that still afford you
(the developer) the greatest amount of power while providing your
users with the least amount of compatibility issues.
Ultimately, dynamic HTML is about exploring what can be
achieved when JavaScript and CSS interact with each other
and how you can best use that combination
to create impressive results.
12. Ajax
• Ajax, or Asynchronous JavaScript and XML, is a
term coined in the article “Ajax: A New Approach
to Web
Applications”(http://www.adaptivepath.com/public
ations/essays/archives/000385.php) by Jesse James
Garrett
• The term Ajax encompasses hundreds of
permutations for data communication, but all
center around a central premise: that additional
requests are made from the client to
the server even after the page has completely
loaded
15. Consistent Development Based - Features
Core JavaScript 1.5: The most current, accepted version of
•
JavaScript. It has all the features necessary to support fully
functional object-oriented JavaScript. Internet Explorer 5.0 doesn’t
support full 1.5, which is the primary reason developers don’t like
to support it.
XML Document Object Model (DOM) 2: The standard for traversing
•
HTML and XML documents. This is absolutely essential for writing
fast applications.
XMLHttpRequest: The backbone of Ajax—a simple layer for initiating
•
remote HTTP requests. All browsers support this object by default,
except for Internet Explorer 5.5–6.0; however, they each support
initiating a comparable object using ActiveX.
CSS: An essential requirement for designing web pages. This may
•
seem like an odd requirement, but having CSS is essential for web
application developers. Since every modern browser supports CSS,
it generally boils down to discrepancies in presentation that cause
the most problems. This is the primary reason Internet Explorer for
Mac is less frequently supported.
