On: You Don't Need JQuery

[teknologist]

Doing ajax without jQuery is also good fun

    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
        if (xhr.readyState === 4) {
            callback(JSON.parse(xhr.responseText));
        }
    };
    xhr.open('POST', url, true);
    xhr.setRequestHeader('Content-Type', 'application/json');
    xhr.send(JSON.stringify(data));

And that's not taking care of errors, edge cases or Internet Explorer at all.

In jQuery:

    $.post(url, data)
