XHR Abstraction

those two functions are the same but with different parameters so try to build one function that receives a method, URL, and other things if you want as parameters.

@MohammedYehia Thanks Mohammed , I did it

function xhrRequest(url, method, data, cb) {
  var xhr = new XMLHttpRequest();
  xhr.onreadystatechange = function() {
    if (xhr.readyState == 4) {
      if (xhr.status == 200) {
        if (method === "GET") {
          var result = JSON.parse(xhr.responseText);
          cb(result);
        } else if (method === "POST") {
          cb();
        }
      }
    }
  };

  xhr.open(method, url, true);
  xhr.send(JSON.stringify(data));
}
