Tipr.js - difficulty understand the usage of the each function !

Hey Guys check out this pluggin tipr.js . 


(Unfortunately i was not able to create a Jsfiddle because there is no CDN available for this plugin. ).

now i downloaded the tipr.js file and if you go through the source code , you will notice that there is an each fucntion. 

on line 21. 

  1. return this .each( function () {
now if i remove that particular line and the corresponding closing brackets on line 46. 

the plugin still works fine , so why really that line ? is it adding some kind of hidden functionality ? or is it making the plugin more efficient ? 

Thank you. 

Guys .
