Example of JavaScript

JavaScript is a programming language that can be used to create interactive web pages. It is one of the most popular languages used to develop websites and applications.

The most basic example of JavaScript is a simple alert message. An alert message can be used to draw the user's attention to some specific information on the page.

alert('This is an example of JavaScript!');

Another example of JavaScript is a basic function. Functions are used to group code together and to make code easier to read and debug.

function myFunction() {
  alert('This is an example of a JavaScript function!');
}

myFunction();

JavaScript can also be used to manipulate the DOM. The DOM is a tree-like structure that represents the HTML of a web page. JavaScript can be used to add, remove, or change HTML elements on a web page.

// Get a reference to the element with the id 'my-element'
let myElement = document.getElementById('my-element');

// Set the background color of the element to red
myElement.style.backgroundColor = 'red';

These are just a few examples of what JavaScript can do. With JavaScript, you can create dynamic and interactive web pages that can respond to user input and create engaging experiences.
