A URL, or Uniform Resource Locator, is the address of another computer, or "server" on the internet. Part of the URL specifies where to reach the server, and part of it tells the server what information we want.
Put simply, a URL represents a piece of information on some computer somewhere. We can get access to it by making a request, and reading the response that the server replies with.
I've renamed the getIssueData() function to getData and made it more flexible. It now takes a URL as a parameter.
