Overview of JavaScript Programming

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 you can build all these applications [Music] welcome back aliens my name is evan reddy 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 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 history again we'll talk about the history of javascript so that we can predict or 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 example in 1993 when websites were getting famous everyone wanted to have their own website but the only way you can interact with the website is one way so basically you request for a page and watch you get a static content of course you can design it but then you do 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 have to make it interactive so netscape came up with this programming language called javascript with the help of sun microsystem and they released javascript in their netscape navigator too so that's awesome right we got a programming language but that was only for the web 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 only use case you can find is building the front end of the web application but then things got 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 application can we use it for building the back end of web as well maybe we can use it for mobile application maybe we can use it for desktop application or maybe we can use it for machine learning and that's where they started using javascript everywhere they were able to do it because of the engine so every browser will be having 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 it has a 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 the help of nodejs 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 is not designed in a normal fashion or the traditional fashion so the moment you talk about javascript everyone want to learn about the html dom elements and how do you change the data on the html page because that's how 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 so there's no harm in learning javascript for the web and then move 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 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 for let's say we will talk about how can we use it for other purpose as well but the idea is to learn javascript from start to end okay now coming back to javascript javascript is actually one of the most famous programming language nowadays and if you go to google and search for top five programming language doesn't matter which article i'm talking about check the first ten links they will mention javascript in top five someone someone might say one or two or three or four or five you will see javascript there okay i've not done that research but i'm quite sure javascript is that famous why is because you can make applications on any platform right and most of the websites in fact as for wikipedia 97 percent of the websites are using javascript for 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 this series we also talk about some facts examples let me give you one fact uh if you know javascript and if you 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 oracle okay so there is a huge history behind 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 also practice it's a programming language right you you can't just look at the video and you can you will remember everything you have to practice practice makes you perfect okay so every time you watch a video do it on your machine i 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 you are for the series bye
