Introduction to JavaScript
● JavaScript is a scripting language running on the web
browser or on the server. It was originally developed by
Netscape and became available in 1995.
● ECMA Script, defined by ECMA-262, is the standard
JavaScript language. ECMA Script defines the very
basic parts of the language

4.
Introduction to JavaScript
● We can embed the code we write in JavaScript into the
HTML page using the <script> element.
<script>
function do_something()
{
alert(”Good Morning!”);
}
</script>

5.
Introduction to JavaScript
● We can alternatively have our code in a separated file
linked with our HTML page.
<script src=”mycode.js”></script>

6.
Development Tools
● We can use a simple text editor. We can alternatively
use an IDE.

7.
Object Oriented Programming
● Every object is a collection of properties (key value
pairs).
var ob = new Object();
ob.name = "david";
ob.id = 132123;
ob.printDetails = function(){
document.write("id="+this.id+" name="+this.name);
};
ob.printDetails();
var other = {name:"david",id:123123);

8.
Functional Programming
● JavaScript allows us to assign functions into variables.
● JavaScript allows us to pass the functions as
arguments.
● JavaScript allows us to define anonymous functions and
supports closure.
var f = function(){
//do something...
}

9.
JavaScript Libraries
● The true power of JavaScript is the huge number of
available JavaScript libraries we can use in our code.
