How do you manipulate the DOM using JavaScript?

In JavaScript, DOM (Document Object Model) manipulation allows developers to dynamically update, modify, and interact with HTML elements on a webpage. This is achieved using various methods to select elements, change content, modify styles, and handle events. Elements can be selected using methods like document.getElementById(), document.querySelector(), or document.getElementsByClassName(). Once selected, their properties can be changed, such as modifying text with element.textContent or element.innerHTML, updating styles using element.style.property, or adding/removing classes with classList.add() and classList.remove(). New elements can be created using document.createElement(), appended to the DOM with appendChild(), and removed using removeChild(). Additionally, event listeners like addEventListener() enable interactive behavior by responding to user actions such as clicks, mouse movements, and key presses. JavaScript’s ability to manipulate the DOM dynamically is essential for creating interactive and responsive web applications.
