Go ahead and setup your Javascript function

First install sublime text 3 from here http://www.sublimetext.com/3 or follow your own way you prefer (I did it with Linux mint Package manager).
Secondly, install package control from here https://packagecontrol.io/installation#st3 (instruction is clearly given in the website so I did not explain it much).
Third, open package control (Shortcut : Ctrl+Shift+P) and search for Package Control: Add Repository Now comes a region to enter URL at bottom part of sublime text 3 window. Enter https://raw.github.com/Grafikart/ST3-LiveReload/master/package.json. Again, open package control and search for Package Control: Install Package and then search for LiveReload in the upcoming window.
Configure LiveReload Package Setting at Preferences > Package Settings > LiveReload > Setting - Default and paste this :

{ 
  "enabled_plugins": 
    [
      "SimpleReloadPlugin",
 "SimpleRefresh"
