JavaScript is an easy-to-use language for front-end programming that allows you to write code in a variety of ways. It was created primarily to make web pages interactive. JavaScript can calculate, modify, and validate data. Programs written in this language are called scripts. Scripts are in plain text format and do not require special training to run.
When JavaScript was created, it was called “LiveScript”. However, since the Java language was very popular in the programming field at that time, its name was changed to “JavaScript”. Over time, JavaScript has become an independent and fully functional language in the programming field. It can be used in both front-end and back-end programming. It is very easy to use because it is integrated with HTML. Therefore, it makes it easy to convert a static web page into an interactive form. In other words, JavaScript adds behavior to web pages.
Why learn JavaScript?
The main reasons to learn JavaScript in the field of front-end programming are:
Suitable for beginners – It comes pre-installed in all modern browsers. It can be learned without installing an additional environment through browsers like Chrome and Mozilla Firefox.
Easy and fast – It allows you to create faster and more responsive websites. Ready-made frameworks and libraries reduce programming time.
It is a versatile language – it can be used for both front-end and back-end programming. In the programming field, JavaScript is now widely used in mobile applications, desktop applications, and game creation.
Some Advantages of JavaScript
Reduces server load: Allows you to verify user input before sending data to the server.
Accessibility and compatibility : JavaScript can be integrated into any web page.
Immediate feedback to the user: The user can receive a warning without refreshing the page if they make any errors.
Flexibility and richness: Various frameworks such as Angular, React, and Svelte increase the functionality of applications.
Interactivity: Various visual changes can be made when the mouse hovers over or clicks.
Rich interface: Drag-and-drop functionality, visual elements such as sliders can be added.
Areas of Use of JavaScript
Adding interactivity to web pages
JavaScript allows users to interact with web pages. It allows you to add dynamism and visual effects to a page. With it, you can do the following on a web page:
Show or hide additional information with the click of a button
Changing the color of an element when the mouse hovers over it
Zoom effect on image
Using the drop-down menu
2. Creating web and mobile applications
JavaScript is widely used in the development of web and mobile applications through various frameworks. The most popular JavaScript framework for mobile applications is React Native.
Angular and Vue.js are widely used for web applications. LinkedIn, Netflix, Uber applications are developed with these technologies.
Game development
JavaScript is also used to create browser-based games. Especially when used in conjunction with HTML5, it is possible to create more interactive and visually rich games. There are many libraries and frameworks (e.g. Phaser, Three.js) that support 2D and 3D game development for this.
Manipulation of HTML pages
Through it, it is possible to add new elements to the page, delete existing ones, and make design changes to suit different devices.
User notifications
JavaScript can be used to display dynamic pop-up notifications to users. These notifications further enhance the user experience of the site.
Background data loading
AJAX technology allows JavaScript to load data in the background while the user performs other actions on the site. This feature allows the website to run faster.
In the programming field, JavaScript is a technology primarily designed for web development, but it is not limited to that. It is both a feature-rich and easy-to-learn language. Due to these features, it is one of the most in-demand programming languages in web development.
