JavaScript AJAX Basics (retiring) AJAX Concepts A Simple AJAX Example

AJAX not getting into action. getting "Not Found The requested URL /sidebar.htlm was not found on this server." error

i have been following along in workspaces but when i launch my preview for the AJAX to get into action i get an error code saying

"Not Found The requested URL /sidebar.htlm was not found on this server."

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function (){
if (xhr.readyState === 4){
document.getElementById('ajax').innerHTML = xhr.responseText;
}

};

xhr.open('GET', 'sidebar.htlm');
xhr.send();

That is how my code looks like in my htlm

//mistyped code
xhr.open('GET', 'sidebar.htlm');

//fixed code
xhr.open('GET', 'sidebar.html');
