getElement by Class Name

In JavaScript, the getElementsByClassName() method is used to retrieve a collection of all elements in the document that have a specified class name. Here’s how it works:
					// Get all elements with the class name "example"
var elements = document.getElementsByClassName("example");

// Loop through the collection of elements
for (var i = 0; i < elements.length; i++) {
    // Do something with each element, for example, log its inner text


This script will retrieve all elements with the class name “example” and log their inner text to the console. Keep in mind that getElementsByClassName() returns a live collection, so if the DOM is modified after the collection is created, the collection will update to reflect those changes.
