What is Full Stack JavaScript

[MUSIC] 0:00 Hi, my name is Reggie Williams, and I'm a developer and teacher here at Treehouse. 0:09 My pronouns are he/him. 0:14 If you have a favorite app or website, 0:16 there's a strong chance that it uses JavaScript. 0:19 Today, I'm going to teach you some of the capabilities of the JavaScript language so 0:22 you can get a better idea of why JavaScript has become so widely used. 0:27 JavaScript was created partly to add interactivity to webpages and 0:32 applications and has grown into a general purpose programming language. 0:35 JavaScript can be used to create games, apps, 0:40 websites, and even control smart devices. 0:44 There are many reasons to learn JavaScript if you're pursuing a career in web or 0:48 software development. 0:53 These include JavaScript's adoption across companies in the technology industry, 0:54 its large online community, helpful documentation, 1:00 and one of the main reasons, its versatility. 1:04 You can use JavaScript in both front-end and back-end development. 1:08 You may know that front-end developers build the presentation layer of webpages, 1:14 working mainly with HTML and 1:19 CSS while using JavaScript to make webpages respond to user interaction. 1:21 Back-end developers focus on writing code that runs on a web server. 1:26 They might write JavaScript to handle form submissions from a user or 1:32 build a database to store and manage data. 1:35 Some developers work on both. 1:39 A full-stack developer knows both front and back-end development. 1:41 Because of this, 1:46 they can take on tasks from working with data to building website layouts. 1:47 One way to think of full-stack JavaScript is like different parts of a car. 1:52 The dashboard interface, pedals, and steering wheel represent the front end, 1:57 allowing the user some control and 2:01 interaction while providing visual feedback. 2:03 Back-end components in this example would include the many parts of the fuel, 2:08 braking, and steering systems, which compute or 2:13 make meaning of the user input to power and control the car. 2:16 You'll learn many amazing things you can do with JavaScript in the front and 2:21 back-end. 2:25 But to start, let's learn more about the language itself. 2:26 Programming languages have common features, 2:30 including their own sets of rules or syntax and predefined keywords. 2:33 In this workshop, I'll teach you more about the basic syntax of JavaScript that 2:39 will allow you to communicate with your computer in a language it understands and 2:44 to start writing your own programs. 2:49
