What is JavaScript? JavaScript applications in the field of web design, applications, etc.
JavaScript is the world’s most widely used, text-based, object-oriented programming language used to make web pages and applications more interactive with visitors. This program has the largest open-source package repository in the whole world. A variety of server coding software (Node.js), productivity applications, 3D games, robots, and IoT (Internet of Things) tools use JavaScript programming.
Java Company’s goal of designing JavaScript has been realized long ago. Their goal is to write code once and apply it anywhere. Learning this programming language is simple and very practical. In this article, you will get to know the uses of JavaScript in different departments.
The relation of JavaScript language with other languages
This language, which is used on both the client and server side, offers advanced features that mainstream languages such as HTML and CSS cannot do. For example, HTML should still be used for the basic structure of websites and apps, while CSS is needed for formatting and prioritizing layouts, as well as controlling how text, images, and other content on a page are presented. In the meantime, Java can enhance these elements and transform them from static capabilities to interactive and exciting capabilities.
These features include Twitter feed refresh, embedded YouTube videos, and more. In other words, JavaScript-enhanced web pages are more dynamic and user-centric, which can bring users back to the site. JavaScript blends well with other programming languages, not just replacing them.

Web developers use JavaScript to improve the sites we interact with every day. Therefore, both developers and site visitors benefit from JavaScript.
This language provides features such as image carousels, media playback on a web page, and displaying countdowns and timers.
Benefits of using JavaScript
Interactivity: Java websites are more interactive and attractive for users; Because this language creates richer and more attractive user interfaces.
Speed: These websites load and run faster; Because JavaScript can be executed immediately in the browser, thus reducing the load on the server.
Simplicity: It is simple to implement and requires only basic knowledge to use.
Integration: Java works well with most programming languages and can be integrated into a variety of applications.
Popularity: Extremely popular. Most websites, regardless of their nature, use JavaScript in some form.
Common uses of JavaScript
JavaScript is mainly used in the following fields:
1. Websites
With JavaScript, you can add a new behavior or action anywhere on a web page. With this, the website can easily interact with the audience and visitors, and there is no need for complicated actions and loading a new page.
Java makes web pages more interactive in a variety of ways, including displaying animations, creating functional drop-down menus, zooming in and out of page images, or even changing the color of buttons when the user’s mouse hovers over them.
2. Web applications (PWA)
With the development of browsers and computers, JavaScript also found the ability to produce powerful web applications. Consider apps like Google Maps. If you want to search for a map in Google Maps, you just need to click and drag with the mouse. At first, the map may seem lacking in details, but it will be completed little by little. JavaScript is working behind this feature.
Web and mobile developers usually use Java frameworks such as Vue, React, and Angular when building mobile web applications; Because they allow the use of common features and functions in many applications. These features include search buttons and category selection options, just to name a few.
3. Show or present
One of the uses of JavaScript is to display or present content on websites. This work is very simple if you are familiar with HTML and CSS programs using the Reveal.js framework.

4. Server applications
JavaScript made its way from the browser to the server a few years ago with the invention of Node.js. After that, big companies like Walmart used Node as the main part of their infrastructure.
5. Web servers
Some developers also choose Node.js as the back-end JavaScript infrastructure to create basic web servers and provide site infrastructure.
You can build more powerful servers with the help of Node or Express.js standard application server framework. Many existing Nodes are built with the help of MEAN (Mango Express Angular Node), of which Express is the main component.
6. Games
Java language is widely used in game development. It is especially suitable for novice developers who want to improve and improve their skills.
Although browsers have not been a platform for old games in the past, they have recently become a convenient place to play games. Additionally, with HTML5 Canvas, the level of sophistication of browser-based games has increased to a great extent. There are even games on the browser that teach us how to program.
7. Fine arts
One of the new features of HTML5 is the Canvas element, which allows browsers to create a 3D space. With this feature, the browser can be used as a new source for implementing digital art projects.
8. Smartwatch applications
The famous company Pebble, which is a manufacturer of smartwatches; Created a small Java framework called Pebble.js so that software developers can build applications for the company in JavaScript.
9. Mobile applications
One of the uses of JavaScript is to create applications for areas other than the web. That is, you create applications that are not placed on the Internet. For example, mobile phones are the most popular way to access the internet. Therefore, all websites must be adapted to display in the mobile version. Now the mobile application should work in both Apple and Android systems. Each of these programs has a different programming language.
10. Flying robots
Some commercial quadcopters that have a simple operating system have found the ability to install Node.js. That is, you can design a flying robot with the help of Java. JavaScript is one of the most accessible programming languages on the planet with many features. Therefore, the applications of JavaScript are very diverse.
The importance of using JavaScript in web design
JavaScript has many practical applications in the field of web design, which we will mention below:
1. Strengthening the web interface (Web Interface)
Today, we are looking to strengthen old and inappropriate web interfaces with the help of Java. These interfaces include clicking on links, entering and submitting information, etc. With these methods, we achieve better interaction and response with the end user. For example, when filling out a profile form or registering for a subscription, does your name appear by default or do you have to reload the page?
2. Word suggestions in the search box
When you type a word in the search box, you will be presented with suggestions based on previously searched information. For example, when the two letters “per” are typed, words like Persepolis, profile and payment are suggested. This pattern is known as Autocomplete.
3. Immediate update of the information
Information that changes continuously is loaded periodically without user intervention. For example results of competitions or stock, market statistics are sent automatically.

4. Loading information upon user request
Users can provide additional information whenever they need; to request For example, the navigation menu on the site contains 6 links, but the display of links will be activated only if the user requests.
5. Solving problems related to website layout and design
Another application of Java is determining the position and location of elements on a page and the dimensions of the browser window. By using this information, you will avoid overlapping elements and other similar problems. For example, if you have a menu with several levels, which requires enough space to check and click. You can prevent the display of navigation bars and overlap between subsections.
6. Upgrade the HTML interface
JavaScript can enhance interfaces derived from HTML. Although it is good to have a text input box, with a Combo box, you can choose the value you want from the list of values provided or enter it. Using JavaScript, you can turn a normal input box into a combo box.
7. Animating the elements inside the page
Java helps to animate elements on the page so that you can display, hide, and fill certain parts of the page and make it functional. With these methods, you will achieve a stronger and better user experience.
Eventually…
Using the Java language does not have many disadvantages. The main issue is that there is a possibility of client-side security breaches in JavaScript code because it is visible to users. However, Java is the most popular programming language today. Given that this programming language is native to web browsers, it’s worth it for new programmers to learn the basics and use it in their projects.
In this article, you get acquainted with JavaScript and its applications in various fields, including web design. JavaScript has many other uses that contribute to the performance of web pages and the user experience. We have covered most of its main uses in this article.
