Hello and welcome.
In this video I will introduce you to JavaScript.
JavaScript is one of the three languages that a web developer must learn what is javascript.
JavaScript is a programming language that adds interactivity to your website.
The interactivity can be when a button is pressed or when data is entered in to a form.
It can even be animations so when you go to a Web site any time you notice some interaction or where
you have to press a button may be complete a form those interactions are made possible by javascript
when javascript is applied to and hasty AML document.
It makes the document dynamic and eat as interactivity to the Web site.
Javascript was invented by Brandon H.
Who is the co-founder of the Mozilla Corporation which also is responsible for the Firefox web browser.
JavaScript is not Java.
There is a completely separate language programming language called Java.
So they are both different in design and other aspects as well.
JavaScript is one of the three language or web developers must learn the other two languages are hasty
AML and CSX.
Another key distinct feature of javascript is that JavaScript is case sensitive so if you declare something
with a lower case and later on tried to access that with an uppercase it will not work because they
are two separate things.
It treats cases separately so uppercase and lower and lower case are two different things in javascript.
So when you write in JavaScript code you need to be careful which are cases for you using lowercase
to define something stick to lowercase so that's it for this introduction to JavaScript.
Thank you and bye for now.
