What the video covers

JavaScript is a versatile programming language used for web, mobile, desktop, and even machine learning applications.
Originally created in 1995 for web front end interactivity by Netscape and Sun Microsystems.
Websites in early 1990s were static and non-interactive, prompting the creation of JavaScript.
JavaScript's popularity grew due to its ease of use and broad community support.
Node.js enables JavaScript to run outside browsers on servers and other platforms.
This course focuses on learning JavaScript as a full programming language, not just for manipulating HTML DOM.
The series will cover JavaScript fundamentals, practical usage, and its applications beyond front end development.
JavaScript consistently ranks among the top 5 programming languages globally.
Approximately 97% of websites use JavaScript on the client side.
The course encourages active practice and experimentation to master JavaScript.

Chapters

What was the original purpose of JavaScript?

JavaScript was originally created in 1995 to make web pages interactive on the front end, allowing users to interact with websites beyond static content.

How can JavaScript be used beyond web front end development?

Thanks to environments like Node.js, JavaScript can run on servers, mobile devices, desktop applications, and even be used for machine learning.

What is the recommended way to learn JavaScript according to this course?

The course suggests learning JavaScript as a full programming language by running it directly on your machine, practicing regularly, and experimenting with code rather than focusing only on web front end.

Speaker A

Imagine knowing a programming language using which you can build any type of application: web application, front end, back end, both, mobile application, desktop application, and even for machine learning. And that language I'm talking about is JavaScript. So, using JavaScript,

Speaker A

you can build all these [Music] applications. Welcome back, aliens. My name is D Ready, and let's get started. So, we are talking about JavaScript, and finally, I'm starting a series on JavaScript. So, first of all, what is JavaScript? Now,

Speaker A

JavaScript is a programming language which you can use to develop any kind of application which we named before. But then, it didn't start in that way. In 1995, when JavaScript was released, it was for a different purpose. It has a different

Speaker A

history. Again, we'll talk about the history of JavaScript so that we can predict the future, and we'll discuss that in a separate video. But let's talk about 1995, when JavaScript came into existence. It was mainly for the web front end. For example, in 1993, when

Speaker A

websites were getting famous, everyone wanted to have their own website. But the only way you could interact with a website was one way. So basically, you request a page, and what you get is static content. Of course, you can design it,

Speaker A

but then you can't interact with that application every time. If you want to move between pages, you have to use hyperlinks. So basically, that website was not interactive. And if you want to keep your audience engaged, you

Speaker A

have to make it interactive. So Netscape came up with this programming language called JavaScript with the help of Sun Microsystems, and they released JavaScript in their Netscape Navigator 2. So that's awesome, right? We got a programming language, but that was only for the web

Speaker A

front end, just to make your web application interactive. And for many years, it was that way. I mean, the moment you think about JavaScript, the only use case you can find is building the front end of the web application. But then things got

Speaker A

changed. Now you can use JavaScript anywhere. The reason is JavaScript was easy, and we have so many people working on this language. So they thought, hey, instead of using JavaScript only for web applications, can we use it for building

Speaker A

the back end of web as well? Maybe we can use it for mobile applications, maybe we can use it for desktop applications, or maybe we can use it for machine learning. And that's where they started using JavaScript everywhere. They were able to

Speaker A

do it because of the engine. So every browser will have a JavaScript engine. So the reason you are able to run the application, of course we'll see that in the practical, but you can run any JavaScript code on the browsers because

Speaker A

it has an engine. Just take that engine, make sure that engine runs on the hardware or the OS which you have. Basically, you can run JavaScript on your OS now or on your machine, right? So just to give you a hint, that is possible with

Speaker A

the help of Node.js. So Node.js is a runtime environment. Imagine a place where you can run JavaScript. Basically, if you have that stuff anywhere, maybe a mobile application, desktop application, machine learning, you can run it. That's the power of JavaScript. Now this course

Speaker A

is not designed in a normal fashion or the traditional fashion. So the moment you talk about JavaScript, everyone wants to learn about the HTML DOM elements and how do you change the data on the HTML page because that's how

Speaker A

JavaScript came into existence, right? Now, that's not the reason why I'm making this playlist. For me, I want to treat JavaScript as a programming language, not only for the web front end. Okay, see, there's no harm in learning JavaScript

Speaker A

for the web and then moving towards other aspects. But it's tricky, right? Once you move from front end to back end, you may not be comfortable. So I will start this series running JavaScript directly on the machine, okay? So that we will not

Speaker A

learn JavaScript only for web but in a proper way so that you will understand JavaScript from start to end. Of course, we will be using that for front end. In between, we will be using it for, let's say, we'll talk about how can we use it for

Speaker A

other purposes as well. But the idea is to learn JavaScript from start to end. Okay, now, now coming back to JavaScript. JavaScript is actually one of the most famous programming languages nowadays. And if you go to Google and search for top

Speaker A

five programming languages, it doesn't matter which article. I'm talking about checking the first 10 links; they will mention JavaScript in the top five. Someone might say one or two or three or four or five. You will see JavaScript there, okay?

Speaker A

I've not done that research, but I'm quite sure JavaScript is that famous. Why? Because you can make applications on any platform, right? And most of the websites, in fact, as per Wikipedia, 97% of the websites are using JavaScript for

Speaker A

their client side. So you don't have an option, right? So we have a different history. We have some awesome facts, okay? So in the series, we also talk about some facts. For example, let me give you one fact. If you know JavaScript and if you

Speaker A

have been working on JavaScript, so I want to know in the comment section who owns the trademark for JavaScript, okay? Pause the video, comment your answer. So let me give you the answer. It's what? Okay, so there's a huge history behind

Speaker A

JavaScript, and it's interesting. So we'll talk about that as well. I hope you are excited for this series. I want to make sure that you learn from start to end, but you have to make sure that you

Speaker A

also practice. It's a programming language, right? You can't just look at the video and you'll remember everything. You have to practice. Practice makes you perfect, okay? So every time you watch a video, do it on your machine. I

Speaker A

would also suggest that you change the code, do some experiments, and that's how you go. So that's it from this video. I hope you're excited. Hit that like button if you want to enjoy the series and also make sure that you comment how excited

Speaker A

you are about the series. Bye!
