    XMLHttpRequest is an API in the form of an object data whose methods transfer data between a client or web browser and a server.
    It provides an easy way to get data from a URL without refreshing the web page. Send data to a web server in the background.XMLHttpRequest is mostly used in AJAX programming.

    <!DOCTYPE html>
    
    <html>
    
    <head>
    <script>
    
    function loadXMLData(){
    
    var xhttp = new XMLHttpRequest();
    
    xhttp.onreadystatechange = function() {
    
    if (this.readyState == 4 && this.status == 200) {
    document.getElementById("data").innerHTML = xmlhttp.responseText;
    
    }
    
    };
    
    xhttp.open("GET", "sample.php", true);
    
    xhttp.send();
    
    }
    
    </script>
    
    </head>
    <body>
    
    <div id="data">
    
    <button type="button" onclick="loadXMLData()">Click here to get data</button>
    </div>
    </body>
    
    </html>
