    function jsonApiRequest() {
        var xhr = new XMLHttpRequest();
        xhr.onreadystatechange = function() {
            if (xhr.readyState === XMLHttpRequest.HEADERS_RECEIVED) {
                print('HEADERS_RECEIVED')
            } else if(xhr.readyState === XMLHttpRequest.DONE) {
                var json = JSON.parse(xhr.responseText.toString())
                console.log("UserId: " + json.userId)
            }
        }
        xhr.open("GET", "https://jsonplaceholder.typicode.com/todos/1");
