    A "Hello World" program in JavaScript is the simplest way to demonstrate output and test that your environment is set up correctly. It can be done in multiple ways depending on where and how you want to run the code.

    Example ā€“ Using Browser Console:

    console.log("Hello, World!");
    Gekopieerd.

    Open your browserā€™s Developer Tools (F12), go to the Console tab, paste the code above, and press Enter. Youā€™ll see Hello, World! printed in the console.

    1. Using console.log() This method prints messages to the browser console, useful for debugging or logging information.

    console.log("Hello, World!");
    Gekopieerd.

    When executed in a browser console or Node.js terminal, it outputs the text without interrupting user interaction.

    2. Using alert() Displays a pop-up dialog box with your message.

    <!DOCTYPE html>
    <html>
    <body>
    <script>
    alert("Hello, World!");
    </script>
    </body>
    </html>
    Gekopieerd.

    Opening this HTML file in a browser will show a modal alert box.

    3. Using document.write() Writes directly into the HTML document during page load.
