12,755 PointsOk, have you ever been surfing the web and received a 404 error (page not found). When a website loads it will also send a status code, if working properly that code will usually be 200. Similar to that, the
onreadystatechangemethod will listen to the browser for a "ready state" code. So, when the request is made, the ready state will be something like 1. Once the file has fully downloaded, the browser will change that ready state property to 4.The state changed because the file asked for finished downloading.
