Stop Chrome Caching My JS Files

New path for Chrome Update Sept 2018:

Click settings icon on the top right corner ... | Settings | Preferences | Developer Tools | Network | Disable cache (while DevTools is open)

A faster way to do this is by right clicking the refresh icon beside the address bar and choosing Empty Cache and Hard reload

Just make sure Chrome's dev tools is open. (Press F12) By the way... This trick only works on Chrome for Windows, Ubuntu, and Mac OS
