JavaScript
In today 's video, we will learn JavaScript from start to end in one video. This JavaScript
video will be exceptional Because I will show you JavaScript. And after that, I will teach
you 2 awesome projects. One will be our to-do list In which we will see how DOM
manipulation is done in JavaScript. In second project we will create a clock. And how to
update it in real time without refreshing the page. I want to be honest with you all and
want to tell you that it takes a lot of hard work to product this type of videos. JavaScript
does run in browsers. So your browser contains everything that is required to run
JavaScript. That means your browser knows how to run. Mostly all the pages on the web
contains JavaScript. So in the script tag , it has written JavaScript. This is the JavaScript
Code. JavaScript gives Strength to the page. That is the logic on the frontend That the
browser has to perform on itself. In browser JavaScript runs in the client side. Client
means the person who is using the internet. That means the computation is not done on
the server. It is being done in your house, your computer. So how is this happening ? Is
there any server ? Who is doing the computation for us ? Even if you disconnect your
internet wire then too you can perform calculations here.
JavaScript is very important. I will show everything step by step What are JavaScript
variables, operators, assignment operators, functions objects objects and functions
objects. And after that we will use a method for coding in JavaScript. We will not write
code here because we want to create programs. How to run and execute those programs
will be very important for us. HTML is a must for developing any website. HTML
contains CSS and JavaScript. JavaScript is used in both frontend and backend. HTML is
the that contains everything It is the skeleton of the website. CSS is for designing. So I
can safely write JavaScript is for Client side scripting. And JavaScript is your memory ,
your brain. HTML is the skeleton of a human skeleton. CSS contains the things that you
need to look beautiful like hairs, nose , muscles etc And JavaScript will be the brain that
thinks and makes use both of these things and helps in working. These were the basic
requirements to build a website.
Web server is like a computer. It is a virtual machine that computes and in response it
returns HTML , CSS , and JavaScript. Processing is done in a fraction of a millisecond.
The CSS and JavaScript will be embedded in HTML. So HTML will host these things
and it will be bundled together and will be sent to your browser. HTML stand for
Hypertext Markup Language. HTML is a Skelton in which there are skeletal buttons
skeleton of forms and input tags without design. CSS is used to present HTML in a better
way. If you create a button in HTML then it will look like this. JavaScript is a high-level
dynamic interpreted language. And it allows client-side scripting. And JavaScript is
different from Java. Java was popular at that time and wanted JavaScript to react Java 's
level So they made it JavaScript for web pages. Script can be executed in the browser
itself.
