  1. JavaScript is a scripting language that brings interactivity, dynamic behavior, and advanced functionality to websites. While HTML structures content and CSS styles it, JavaScript enables the page to respond to user actions, update content without reloading, and interact with external data sources.

    Core capabilities include:

    • Dynamic content updates – Modify HTML and CSS in real-time via the DOM API.

    • Event handling – Respond to clicks, key presses, form submissions, etc.

    • Data manipulation – Store values in variables, process strings, and perform calculations.

    • Multimedia control – Play audio/video, capture webcam input, or animate graphics.

    • API integration – Fetch data from services like Google Maps or weather APIs.

    Example: Adding interactivity to a button

    <button type="button">Player 1: Chris</button>

    <script>
    function updateName() {
    const name = prompt("Enter a new name");
    button.textContent = `Player 1: ${name}`;
    }
    const button = document.querySelector("button");
    button.addEventListener("click", updateName);
    </script>
