Usman Sabuwala you are right, it's the easiest way to do it.

good post but I must suggest you mention that the document.execCommand('copy'); is not a good solution, knowing that it might be removed at any time from any browser, See Docs and you can advise people to use a more stable and safe method as the Clipboard API still the best solution for me is to use them both, I can use the Clipboard API and the .execCommand() as a fallback
