JavaScript is a robust programming language that can be applied to an HTML document and used to create dynamic interactivity on websites. It was invented by Brendan Eich, co-founder of the Mozilla project, the Mozilla Foundation, and the Mozilla Corporation.
You can do almost anything with JavaScript. You can start with little things like carousels, image galleries, fluctuating layouts, and responses to button clicks. With more experience, you'll be able to create games, 2D animations and 3D graphics, embedded database-driven applications, and much more!
JavaScript itself is fairly compact yet highly flexible, and developers have written a host of tools on top of the core JavaScript language, unlocking a great deal of additional functionality with minimal effort.
Here we'll actually start to look at some code, and while we're at it, we'll explore what actually happens when you run JavaScript on your page.
Let's briefly recap the history of what happens when you load a web page in a browser. When you load a web page in your browser, you are executing its code (HTML, CSS, and JavaScript) within an execution environment (the browser tab). This is like a factory that takes raw materials (the code) and generates a product (the web page).
JavaScript syntax is based on the Java programming language and is easy to learn and code. JavaScript is used by developers on almost any website and mobile app for client-side scripting. Node.js has grown in popularity for writing backend code over the past decade. Several of the major streaming and video platforms have been coded in Node.js.
Unlike other programming languages, JavaScript can be embedded into any web page and used with many other web development languages and frameworks. Once you've written it, you can run JavaScript code on any machine. In this way, JavaScript technology allows application development to be platform independent.
You can use JavaScript to reduce server load and network congestion by making it possible to run logical operations and do much of the server work on the client itself. For example, consider the process of completing a registration form. JavaScript quickly checks if you have entered a 10-digit number for the "mobile" field. If these requests were sent to the server, the page would reload for every error, making the registration process very slow and tedious.
JavaScript creates sophisticated websites that make it easy to find and process complex information. Developers use JavaScript to extend functionality and readability, as well as to make user interaction with the website more efficient.
