How can JavaScript be effectively utilized to handle button clicks in PHP applications?

JavaScript can be effectively utilized to handle button clicks in PHP applications by using AJAX to send asynchronous requests to the server when a button is clicked. This allows for dynamic updates to the page without needing to reload the entire page. By using JavaScript to handle button clicks, you can create a more interactive and responsive user experience in your PHP application. 

<button id="myButton">Click me</button>
<div id="result"></div>

<script>
document.getElementById("myButton").addEventListener("click", function() {
  var xhr = new XMLHttpRequest();
  xhr.open("GET", "process.php", true);
  xhr.onreadystatechange = function() {
    if(xhr.readyState == 4 && xhr.status == 200) {
      document.getElementById("result").innerHTML = xhr.responseText;
    }
  };
  xhr.send();
});
</script>
