While HTML and CSS code are used to create static web pages, JavaScript allows users to interact with them on the fly.

An example of a function is a button that changes its message as the user clicks it. A similar example is a counter that increases as the number increases. This is possible because of the nested nature of JavaScript.

In JavaScript, the code is server-side. The code is displayed in the HTML, but remains fully visible in the source code. For this reason, the code is stored in a separate.JS file. For example, a basic function in JavaScript would add two numbers. It is called “add()” with the parameters 7 and 11, which results in the value “18”. Then, the user would see the alert box.

JavaScript is a lightweight interpreted programming language. It provides a framework for building rich and interactive web applications. It also makes it easy to develop dynamic web applications.

This way, the script can be used for a variety of tasks.
