    In JavaScript, handling button click events is a common task that can be achieved using different methods. These methods allow you to execute specific functions when a button is clicked, providing interactivity to your web applications.

    Using the onclick Attribute

    The onclick attribute is a straightforward way to handle click events directly within the HTML. You can specify the JavaScript function to be executed when the button is clicked by adding the onclick attribute to the button element.

    Example:

    <button onclick="changeColor()">Click</button>
    Copied!

    In this example, the changeColor function will be executed when the button is clicked. The function can be defined in a <script> tag within the HTML or in an external JavaScript file.

    JavaScript:

    function changeColor() {
    const name = document.querySelector(".name");
    name.style.color = "blue";
    }
    Copied!

    This function changes the color of the text inside an element with the class name name to blue.
