What is JavaScript used for?

JavaScript is a text-based computer language used on both the client and server sides that makes interactive web pages possible. JavaScript adds interactive features to online websites to keep users interested, while HTML and CSS are languages ​​that provide the structure and design of web pages. JavaScript is often used in everyday applications, such as the search bar on Amazon, embedded news summary videos in the New York Times, and refreshing the Twitter feed. The incorporation of JavaScript enhances the user experience by converting static web pages into interactive web pages. All in all, JavaScript gives web pages their behavior.

JavaScript Application

Web browsers and web-based applications are the primary uses of JavaScript. JavaScript is used in software, servers, embedded hardware control, and networking. Here are some simple applications using JavaScript -

Improve the interactive functions of the website

Users can interact with web pages using JavaScript. Here are just some of the uses for JavaScript on the web; there are almost no limits to what you can do with it -

• You can show or hide more information with the click of a button.

• On the website, scroll through the carousel of photos.

• Enlarge or reduce the picture

• Website use timer or countdown

• In-page audio and video playback

• Animation and display

• Use the hamburger drop-down menu

Build online and mobile applications

Developers can use different JavaScript frameworks when creating online and mobile applications. The basic framework for creating a website or online application is a JavaScript framework, which is a set of JavaScript code libraries that provide developers with ready-made code for common programming functions and tasks.

Famous front-end JavaScript frameworks include React, React Native, Angular and Vue. Node.js, a JavaScript runtime environment based on the JavaScript V8 engine Google Chrome browser is widely used by businesses. Paypal, LinkedIn, Netflix, and Uber are some famous examples.

Create a Web server and create server software

Developers can use JavaScript to create basic web servers and Node.js to create back-end infrastructure beyond websites and applications.

Over the past decade, JavaScript has moved from browsers to servers as NodeJS has expanded. Since then, major enterprises including Walmart, LinkedIn, and Uber have used Node as a vital part of their backend architecture.

Of course, you can build a more durable server using NodeJS or the universal server application framework ExpressJS. The MEAN stack consists of Express and Mongo, Express, Angular, and Node, and is used by many of the Node-based applications discussed previously.

Video Game Development

Of course, you can also use JavaScript to make browser games. These are great resources for novice developers to hone their JavaScript skills.

Quadcopter coding

Many commercially sold quadcopters come with a base operating system on which NodeJS can be installed. This means anyone can program drones using JavaScript.

Presentation

Especially among developers, PowerPoint and Keynote are not the most popular programs. The RevealJS package was most likely created for this purpose, making it easy to create presentations as web pages using HTML, CSS, and JavaScript. Slides.com uses RevealJS to create web-based slideshows. Therefore, even those who are new to network programming can utilize it for presentations without even realizing it.

Art

The canvas element in the 2014 HTML5 standard enables browsers to generate three-dimensional forms, which is one of the fascinating features. As a result, digital art projects now have a new medium in the browser.

Programming Difficulties

Every December, hundreds of developers sign up for Advent of Code, a 25-day coding challenge series. Although developers can use any language to complete these daily challenges, JavaScript is a common choice.

Adaptive Map

Map creation is a great use of JavaScript. They may have information about overlapping, zooming in and out, and panning areas. Even maps of places that don't exist in reality can be created using JavaScript.

Virtual Reality

Virtual reality is a very new and interesting discipline whose boundaries are still being discovered. Everyone uses it, including gamers, doctors, and interior designers. JavaScript makes working in VR more powerful.

in conclusion

JavaScript and programming in general can be considered obscure and intimidating. But if you start from the right place and grow your knowledge and abilities in tiny logical stages, there's no reason why you can't become a proficient JavaScript developer.
