What is the Use of JavaScript? Familiarity with 6 wonderful applications of JavaScript!
JavaScript is one of the most widely used software design and development programming languages. A 2019 StackOverflow survey found that 69.8% of developers use JavaScript more than any other language. In recent years, JavaScript has been one of the most popular languages among developers and an in-demand skill for businesses, with 95.1% of sites using it. There are various resources in the field of JavaScript training. In this article, we will introduce you to the use of JavaScript in the web world and the miracle of this particular language.
What is JavaScript, and what are its uses?
JavaScript is an object-oriented, interpreted, full-featured, and lightweight programming language many websites use to script web pages. When applied to an HTML document, JavaScript enables dynamic interactivity on websites.
JavaScript helps users build modern web-based applications. JavaScript makes it possible to produce these applications without reloading the page after each interaction.
JavaScript has a very high speed, and this point makes the rate of websites and programs increase as well. It enables developers to maintain and upgrade easily. It should be noted that JavaScript has a straightforward debugging process. It can also be used alongside other programming languages, making JavaScript an excellent choice for web development. Some of the most common uses of JavaScript include:
- Web Development
- Web-based applications
- Web servers
- Mobile apps
- Development of games
- dynamic web pages
JavaScript applications in web development
JavaScript is commonly used to create dynamics and add special effects to web pages. In response to the question of using JavaScript in web development, it should be said that JavaScript enables the interaction of websites with visitors. This language equips websites with interactive tools such as notifications and alerts and can add animation to images and text.
JavaScript is used on websites to validate data; That is, users are ensured to enter the correct information in the fields in the forms. JavaScript also supports external applications such as Flash, PDF, and widgets. Users can also use JavaScript to load content on a website without reloading the entire page.
Applications of JavaScript in the development of web-based applications
As browsers continue to improve, JavaScript has become famous for building powerful web-based applications. One of the most important examples is the Google Maps application. In this program, the user can only click and drag the map in different directions using the mouse. Viewing the details of the maps can be done with just one click. JavaScript is very suitable for developing web-based applications; Because it does not need expensive web servers. Instead, all code is processed on the user side. Thus, the load on the server is reduced, and the program is loaded more efficiently.
The use of JavaScript in web servers
JavaScript combined with Node JS can be used to create web servers. Because Node JS is event-driven, it moves quickly to the next task without transferring vast amounts of data, making JavaScript web servers so fast.
Node JS servers use single-threaded processes, meaning commands are executed simultaneously. The techniques are simple, and thus, there is less scope for error. JavaScript servers make it easy for developers to manage concurrency and detect errors that can be difficult in multithreaded processes.
The use of JavaScript in mobile applications
JavaScript is often used to develop cross-platform mobile apps for iOS, Android, Windows, and Blackberry. Some of the most widely used JavaScript frameworks for mobile apps include jQuery Mobile, React Native, Apache Cordova, and Titanium. These frameworks are free and open source and have dedicated community support.
Many mobile JavaScript frameworks are lightweight; This means that they allow fast loading for programs. These frameworks also usually support a wide range of screen sizes and screen resolutions.
Application of JavaScript in game development
JavaScript is increasingly used to create games such as Angry Birds, Polycraft, and Bejewelled. If JavaScript is used in conjunction with HTML5, it can create influential games that require nothing more than a keyboard to run. This combination opens up a wide range of engines, libraries, and a variety of standard web languages that can be used to create fully interactive games.
JavaScript has various libraries and frameworks for creating games. The game can be 2D or 3D. Some JavaScript game engines like PhysicsJS and Pixi.js help us to create a web-based game.
The use of JavaScript in dynamic web pages.
Dynamic websites have various interactive elements, such as buttons, forms, and polls controlled by server-side scripts. JavaScript allows developers to add these elements to a web page to make the website attractive and technically functional.
Since JavaScript is an event-driven programming language, it loads code quickly, meaning content is displayed without delay. This point is critical; Because dynamic websites and web pages need to load quickly to keep visitors interested. It’s good to know that pages that load within two seconds leave an average of 9% of visitors, While for pages that take five seconds to load, 38% of visitors abandon them.
Another advantage of JavaScript software development is its integration with other programming languages. So, if you have a static website written using a different programming language, you can add some JavaScript code to make your page dynamic.
What is full-stack JavaScript, and what is its use?
The full stack includes all web application layers, from the technologies it runs on to the database, user interface, and business logic for the front end. A full-stack JavaScript developer can work with both backend and frontend code to build a web-based application, all written using JavaScript. Full-stack JavaScript is very popular right now.
Several companies use the full-stack JavaScript convention and employ full-stack software engineers, Including:
- Facebook Inc
- apple company
- Netflix Inc
- Amazon Inc. (AWS)
- Most startups
Java Script; The modern language of the web world
JavaScript, often known as JS, is a programming language that, along with HTML and CSS, forms one of the foundations of the World Wide Web. Reports show that 98% of websites use JavaScript. In this article, we mentioned six primary uses of JavaScript. Still, it must be said that this popular programming language has many uses that are not limited to the mentioned ones.

IT technology is developing day by day, and one of the essential foundations of its development is programming knowledge. People who have started learning to program today and have taken steps in this way in the coming years can reach very high millions of incomes, which shows the importance of IT and programming.
