Why Java Script is needed?

JavaScript is most commonly used as a client-side scripting language, which means that JavaScript code is written into an HTML page. When a user requests an HTML page with JavaScript in it, the script is downloaded in the browser of the client machine.

JavaScript is used in many contexts, like generating pop-ups, navigation menus, dynamic content loading, etc. In the next tutorials, we will discuss different applications of Java Script.

Advantages of using JavaScript

---

• Less server interaction: A user input can be validated by JavaScript before sending the data to the server for reducing server computation.
• Less server traffic: JavaScript is used to reload the content of a page segment instead of reloading the whole page.
• Interactivity: It is used to create web interfaces that react to users' activities, like mouse movement or keyboard actions.
• Rich interface design: JavaScript is also used to include drag-and-drop components and sliders to give a Rich Interface Experience to the visitors.
