The document provides information on JavaScript fundamentals including:
- JavaScript is an object-oriented scripting language used to make web pages interactive. It was originally called LiveScript and developed by Netscape.
- JavaScript can be used for both client-side scripting in web browsers and server-side scripting using Node.js. It is an interpreted language that is loosely typed, prototype-based, and supports operators, control structures, and functions.
- Common uses of JavaScript include form validation, dynamic updating of content, and basic interactivity on web pages. It works with HTML and CSS to create dynamic web pages.
Java Script is one of the most pervasive languages found on the internet and World Wide Web. Java Script is useful in making web pages more interactive. The pages can be made to react to the actions of the users in the form of special effects, both visual and otherwise.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. JavaScript is Java code written
in browsers!
JavaScript can be
used to do server
side code as well
JavaScript is
programming
language
JavaScript
make
webpage
look more
beautiful!
JavaScript are
very slow and
unpredictable!
Myths or Facts Let us discover
3. JavaScript
Is a scripting language developed by Netscape, and
later standardized by W3C.
It was originally called LiveScript.
Used not only for web client and server side web
programs, but also for iPhones, Adobe Photoshop,
Adobe Flash action script to name a few.
JavaScript on web page works with HTML and CSS
to create a DHTML page.
Our focus
4. Scripting and Programming language
Script are line of code that does not execute stand-
alone. They run on browser (client-side) or
application server (server-side) or on top of some
other application.
They are interpreted at runtime and are not
compiled.
Usually are loosely-typed language.
Examples: JavaScript, JScript, VBScript, PHP
5. Is JScript not
same as
JavaScript?
JScript is
Microsoft version
scripting
language which is
very similar to
JavaScript
Oh! I
thought it
was
VBScript
Microsoft produced 2
scripting languages-
VBScript –(syntax similar
to VB)and JScript
6. JavaScript in a Web Page
To create more interactive pages- client side validations
etc.
To generate html dynamically.
Event handling
To enhance browser capabilities by giving it a better
look – printing on status bar etc.
Interaction with embedded components like applets and
active x controls.
8. Where will the code be written?
Email format
validation
Password validation
Changing the colour
of the page based on
user’s input
Displaying different
page based on the
user’s role.
Refreshing just part of
the page
Client-side
JavaScript code
Server-side code
9. Language Features
Syntax similar to C++ and Java
Case sensitive
Loosely typed
Interpreted
Platform independent
Object-based language
Semicolon, as separator for multiple statements
in the same line.
10. Object-based language
Also called prototype-based object oriented language
Object-based language
JavaScript objects are associative arrays
functions as object constructors and
methods
prototypes instead
of classes for inheritance.

11. Simple Scripts in HTML
<HTML><HEAD><TITLE>Hello</TITLE></HEAD>
<BODY>
First java script code<br>
<SCRIPT type="text/javascript” >
//Java script single line comment
alert(“Hello java script”);
/* java script script
multi-line comment */
</SCRIPT>
</BODY>
</HTML>
popup
What will happen if you
run this on a browser
that does not support
JavaScript?
12. NOSCRIPT and Hiding scripts
Because some browsers don’t support
JavaScript it is wise to put the JavaScript code
inside HTML commented tags.
<SCRIPT type="text/javascript” >
<!—
alert(“Hello java script”)
-->
</SCRIPT>
<NOSCRIPT>
Java script is not supported
</NOSCRIPT>
• The text inside the <NOSCRIPT> tag will not be
processed by the JavaScript aware browsers.
13. External Script
Scripts can also be written in a separate file and
can be referenced in a HTML file.
<HTML><HEAD><BODY>
<SCRIPT type="text/javascript”
SRC=“jsfile.js”>
</SCRIPT>
</BODY>
</HTML>
alert(“Hello”);
jsfile.js
Path can be
1. Absolute path
http:://server1/get.jsp
2. Root relative:
/scripts/jsfile.js
3. Document relative
../scripts/jsfile.js
Why would you want
to write JavaScript in
another file?
14. Placeholders for scripts within HTML
Inside head
only declarations. Declarations could for variables or functions.
No standalone executable statements must appear
Inside the body
any statements can appear
standalone executable statements inside the body are interpreted in
place where it appears.
Along with the event handler
Script expression can be written as a value when an event like button
click happens.
15. Data types
Data types supported by Java Script are
a) Numeric – integer and floating point numbers
(64 bit, IEE754 floating point)
alert(5+154e-2);
b) String-
alert(“Hello”) ;or
alert(‘Hello’) ;
c) Boolean- true, false
16. alert(’God gives every bird it's food
but he doesn't throw it into it's
nest’); gives me error
Hey! use escape sequences
alert(’God gives every bird
it's food but he doesn't
throw it into it's nest’);
Yes ! escape sequences can be used or you
could also use double quote for string
literal.
alert(“God gives every bird it's
food but he doesn't throw it
into it's nest”);
17. Variables and Data types
Variable names must begin with a letter, under-
score or $, subsequent characters can be a letter,
under-score or $ or number.
They can be assigned with proper value and used
where ever appropriate . They are called data
stores.
To declare a variable:
var x;
var x=1; declare and initialize
Variables declaration is not compulsory in
JavaScript. (If you don't declare a variable explicitly,
JavaScript will declare it implicitly for you.)
21. NaN
true
false
Infinity
1
0
false
alert(10/"abc");
alert(1==true);
alert(1=="true");
alert(5/0);
alert(true & "3");
alert(true & "a");
alert(10/"abc"==NaN);
Then how do we compare
NaNs?
Use isNaN()
No we cannot,
because ‘a’ is a string.
We will look at the
methods of String and
there we will check
out if we can do the
achieve the same.
22. Shift operators
The shift left operator looks at the integer to the left of the operator as a 32-bit binary
number.
>> the SHIFT RIGHT operator
<< the SHIFT LEFT operator
>>> the UNSIGNED SHIFT RIGHT operator
s=2;
t=-2;
alert((s<<2) +" "+(s>>2)+ " "+(s>>>2));
alert((t<<2)+" "+ (t>>2)+ " "+ (t>>>2));
Result of popup:
8 0 0
-8 -1 1073741823
Find what
happens when
you shift beyond
32 bits?
23. === and !==
alert("34"==34);
Returns true
alert("34"===34);
Returns false
=== and !== are used for stricter comparisons
based on types.
Note that alert(34.0===34) returns true
alert(true===1); returns false
24. Control statements
Same as in C++ or Java
if else
for
for..in
while
do .. while
switch
25. Getting input from user
String prompt(question,defaultanswer)
Example: prompt(“what is your
name”,””);
A prompt box pops up. The user can enter some text
and click either "OK" or "Cancel" to proceed after
entering text.
If the user clicks "OK" the box returns the input
value.
If the user clicks "Cancel" the box returns null.
26. Function
Like other programming languages, in JavaScript
also we can define a reusable code-block which
will execute when ever it is called.
A function can be defined inside <head> ,
<body> or in a external file and can be called
from anywhere after it has been read.
Syntax
function functionname(var1,var2,...,varX)
{
//some code
}
28. Calling a function
The above function can be called as
display();
display(“hello”);
Or display with any number of arguments
function display(x){
if(x==null)
x=“Greetings”;
alert(x) ;
}
You can also pass values to a function that does not take
any arguments!
30. Local and Global variables
All the variables that are not explicitly declared are global.
Local variables are created using var inside the function
Global variable
Error.
<html><head>
<script>
total=0;
function sum(){
y=20;
var x=10;
total=x+y;
}
function display(){
sum();
alert(total);
alert(y);
alert(x);
}
Local variable
