Manipulating the Document Object Model (DOM) enables developers to build engaging interactive experiences on the web by programmatically generating HTML elements at runtime.

With JavaScript, you can add, remove, update, clone, and even copy styles across existing and newly created DOM nodes.

Let’s explore essential methods for crafting dynamic applications.

Prerequisites

Prior experience working with HTML, CSS, and familiarity with basic JavaScript concepts is encouraged before tackling this subject matter. If needed, consult learning platforms like MDN Web Docs, freeCodeCamp, or Udacity to strengthen foundational knowledge.

const button = document.createElement("button");
button.id = "myButton";
button.innerText = "Click me!";
