10 Practical Applications of JavaScript And Tips
JavaScript is widely used on the internet. JavaScript is the most widely used programming language; 97.7% of all websites use it for client-side programming. For this reason, having knowledge of JavaScript is essential if you want to work as a web developer.
Learn how to use JavaScript, why it's so popular, some useful applications for it, and how to become a skilled JavaScript developer to jumpstart your web development career.
Developers utilize JavaScript (JS), an object-oriented, cross-platform programming language, to create interactive web pages. It enables developers to work with animations, pop-up menus, clickable buttons, manage multimedia, and more. It also lets them construct dynamically updated content. JavaScript can be used on the client side as well as the server side. Web pages are styled and given structure by the HTML and CSS languages; interactive components that engage users are added by JavaScript. 90% of websites on the Internet would be static without JavaScript.
JavaScript is used by almost all of the computing devices we use today, including Mac OS, Windows, Linux, Android, iPhones, and Smart TVs. The following important factors contributed to JavaScript's widespread adoption in web development:
A lot of websites and online apps are built with JavaScript. Let's talk about a few real-world uses for JavaScript in different sections.
The scripting language used to create web pages is called JavaScript. With the help of JavaScript, which was developed for Netscape, programmers can create dynamic and interactive websites that let users interact and carry out intricate tasks. Additionally, it lets users add material to a document without having to refresh the whole page. JavaScript is used by the majority of websites for external program support and validation, such as PDF documents, widgets, and Flash apps. JavaScript is used by some of the biggest software companies in the world to enhance user experience.
Several well-known websites, like Google, YouTube, Facebook, Wikipedia, Yahoo, Amazon, eBay, Twitter, and LinkedIn, are among those that employ JavaScript.
Robust online apps are developed using a variety of JavaScript frameworks. All users need to do to explore a map in an application like Google Maps is click and drag the mouse to get a detailed view. JavaScript powers this, interacting with the browser without contacting the servers. React Native, React, Angular, and Vue are popular JavaScript front-end frameworks that aid in the development of online applications. Application Programming Interfaces (APIs) and the AngularJS JavaScript framework were used in the development of Netflix and PayPal.
Using JavaScript to create interactive webpages with presentations is a relatively common use case. Using HTML, web-based slide decks may be created with the RevealJs and BespokeJs libraries. Interactive slide decks with transitional styles, themes, and slide backgrounds in all CSS color formats may be made with the RevealJs tool. The BespokeJs framework is packed with capabilities, such as dynamic bullet lists, resizing, syntax highlighting, and more. With JavaScript, users can create websites and presentations even if they are not very proficient in programming languages.
JavaScript is also used with the open-source Node.js runtime environment to create server-side applications. Coders are capable of creating, testing, and debugging code for scalable and quick network applications. JavaScript facilitates HTTP request management and content generation. Prominent corporations such as Uber, Walmart, PayPal, GoDaddy, and numerous others have embraced Node.js for their server architecture.
Using Node.js, developers may create a web server with JavaScript. Because Node.js is event-driven, it doesn't wait for the previous call's response before moving on to the next one. The servers send large amounts of data without buffering very quickly. The createServer () function is used by the HTTP module to create servers.
Another significant use for JavaScript is in the creation of online games. When creating games using JS, HTML5 and JavaScript work together quite well. Rich graphics for games are provided via the EaselJS library. Complete online access is possible with HTML5 without the need for other plugins like Flash. HTML5 and JavaScript provide the foundations for sophisticated browser games like Tower Building, CrossCode, and HexGL.
The canvas element, a more recent addition to HTML5 in JavaScript, makes it simple to create 2D and 3D graphics on a web page. Numerous browser-based digital art projects have benefited from this. Become a digital artist by writing your own JavaScript code.
Pebble offers a JavaScript framework called Pebble.js that enables programmers to write JavaScript apps for Pebble watches. Write some simple JavaScript code to create a smartwatch app.
Developing applications for non-web settings, or for objects that are not on the Internet, is one of JavaScript's most potent uses. With the popularity of mobile devices at an all-time high, JavaScript frameworks have been developed to make it easier to create mobile apps for several operating systems, including Windows, iOS, and Android. Cross-platform mobile app development is made possible by the React Native framework, which gives developers access to a universal front end for both iOS and Android.
Not to mention, you can program a flying robot using JavaScript. Users can operate various miniature robots, inventive maker projects, and Internet of Things devices with the help of the Node.js environment. Discover the fascinating world of JavaScript-powered drones, flying robots, and quadcopters.
