JavaScript TutorialIn 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.
Node. js is web server. It can be executed on the browser as well as the server. JavaScript is a
safe language when you run it in the browser. CoffeeScript and TypeScript have been transpiled
