I mean things like two deeps animated insiders force with privilege, validation slided partners, galleries with companies and many men, and more and well you might be asking yourself what you will know after discourse.

I don't like to talk about myself, but well, as you can see, I have got an experience in this matter. I've been programming for over 10 years time and I have been developing a website for over 14 years and I am altered off 27 video courses in Poland. I have created also six video courses in English. I am teacher off thousands off satisfied customers. There are many comments about my courses and here is one of them. If you have any questions regarding cover topics, please just ask me.

What you will know after this course?: Hello today I would tell you about his JavaScript and why it's worth to learn. JavaScript is a programming language for Web browsers. So, for example, for Firefox, Google, chrome, Internet spur and so on, you can create in Eat a coat, which is called a script that can be executed on the visitor off your website computer, which means that when you finish loading the website, so let's refresh it is you can still access elements on the website and you can change them , right? So, for example, when we have got here a gallery with calmness with these miniatures here, as you can see when I am using my mouth over one of the aim it the image here, the main image is being changed, and it's very useful because now you don't need to take so much space on your website, and you can show the product in the bigger version very easily. Right. As you can see, this is improving the user experience on your website and in addition to these, as you can see, we have got a tool tip here, right that is giving additional information about each off this image that is very very cool and it's improving, um, their user experience. So HTML is responsible for the content of the website. CSS is responsible for the layout and JavaScript. It is responsible for reacting to the user actions and doing things with HTML and CSS on the user side after finishing the download of your website because normally without JavaScript, you wouldn't be able to do anything on the user computer, right, because after connecting to the server your and down holding the website, the user is not connected to the server anymore. It's just look his computer. That's all you could. You could close the connection. You have got still access to this website, right? So javascript can be used for also many other things. Not only galleries with combines, you can create something with this called slided panels. You can create things like transitions between images, well, images that are changing each seconds. We just could slide show panel. You can use it, for example, on shop webpages, where you can show many products in one small place, right. You can create promotions and many other things which makes your user experience better, and JavaScript is necessary for becoming front and developer who is responsible for the things that are done on the user side. Right. Imagine a situation like that where you have a clock on your website. You would need toe every second request to the server from the server and you value in orderto update this clock. We've javascript. Everything is a rounding on the user side. We were reconnecting constantly to the server So the javascript can be used toe ab the content off your website and placed a dif. You can, for example, change the size right and can show something. You can create a tool tip next we that if you can, for example, change their source attribute of the image here you can do some kind of animation. All that things are done in Java keeps changing dynamic. Anything's layout on your website is something that is down in javascript. But once more there are advanced libraries for javascript like Ajax that advise you to connect to the database and retrieve in for without reloading the website, for example, when we go here, as you can see now, when I click here, I am not reloading my website. I'm just changing. Displace you and all that content is taken from the database from the peach being my school . If you don't know it yet, don't worry. Just remember that you can even use it for in with advanced libraries to create literary website that do not reload refresh, Don't do something like that, right? Refreshing. That takes loads of time. Right? So this is very, very awesome. And you can also use javascript toe pre value date. The input informs like, for example, with the password was strong enough for the email use, right and so on. Before sending these values to the server, you can show special box informing user what is wrong in the form we've other resetting resetting his values in four. It makes user experience on your website. Loads of better understanding, double skip syntax. Well, we allow you to also understand better something would just called Jake. We're a framework. And Jake wear for framework. Visibly beak, library off useful JavaScript, blue jeans functions. Thinks that allows you to write less coat doing much more. Okay, there are already many things done that you can just use, but in order to understand Jake Query, you have toe also I understand. JavaScript. So you so you know what's going on there Right after my cause? You will understand all JavaScript, advanced compliments. So you will be able to use any libraries. As you wish. So you know javascript perfect. This is the most organized cars about JavaScript, from beginner to expert on the whole Internet. I would take you step by step from the theory to practical examples like Amy sliders and animation. If you have any questions, feel free to ask and diesel in the lesson. Thank you very much. 3. Downloading and installing editor : Hello everybody. Today it's time to download an editor that we're gonna use to learn java script. As you can see, we can now use then the beans that you can download from this side here. As you can also see, it can be used to programming in Java to create websites using HTML5, PHP and much, much more. That's why this editor is pretty cool. I really like it. And it's also free. But you might be asking yourself, hey, you know Iraq, I know other programming languages and I've already programmed in other editors. Do I need to use NetBeans? And if I want to follow, you know, you don't, you can use an IDE, you want, you can use an integrated
