Welcome back.
In this video, you will learn what especially BHB is also a programming language, but it doesn't run
in your browser.
Your browser does not understand BHB YouTube so understands BHB, but your browser understands only
JavaScript.
So let's take the example of Facebook dot com.
So when I opened my Facebook, it chose my name.
When you open your Facebook, expose your name and when you press some buttons and send me a message,
those things also happen.
Those happen using JavaScript.
But the name to my name and my photo comes without you doing anything.
You just login, you see your name and your photo.
That logic is decided server side using PSP or some other programming language.
I think YouTube is using Python, but Facebook users BHB.
So when you open Facebook dot com, Facebook makes some set of checks and understands who is asking
for this and then they find your name there and they include your name in the e-mail and they send back
to you.
That's how you see your name.
All the logic, all that thinking which happens in the server is written using BHB and whatever happens
in your browser happens using JavaScript.
So that's the difference between BHB and JavaScript.
Both are programming languages, but JavaScript runs only in your browser, runs only in the server.
So you in the next do.
