    The DOM (Document Object Model) in JavaScript is a tree-like representation of an HTML document, where each HTML tag, attribute, and text is a node. It allows JavaScript to access, modify, add, or remove elements dynamically without reloading the page. The DOM is standardized by W3C and WHATWG, ensuring cross-browser compatibility.

    Example – Accessing and Changing Content

    <!DOCTYPE html>
    <html>
    <body>
    <h1 id="title">Original Heading</h1>
    <button onclick="changeText()">Change Text</button>

    <script>
    function changeText() {
    let element = document.getElementById("title");
    element.textContent = "Updated Heading via DOM!";
    }
    </script>
    </body>
    </html>
    Cóipeáilte!

    Here:

    • getElementById() selects the element.

    • textContent updates its text.
