Force Download with JavaScript

Force download scripts have been an important part of internet usability for a long time.  I can attest to that by the number of times I’ve implemented this feature on the server side and the popularity of my PHP Force Download post, even to this day.  With the web world having moved much more the client side, I started looking for a method to force download without the need of a server, and I found it….right in the Firefox DevTools Debugger!
