JQuery best practice, using $(document).ready inside an IIFE?

Question

I am looking at a piece of code:

(function($) {    
   // other code here    
 $(document).ready(function() {   
    // other code here    
  });    
})(jQue         


        

Answer 1

IIFE needs to create a one more scope. If you remove IIFE and $ will no be defined (ie jQuery.noConflict()) - you will get an error. jQuery will defined everywhere the javascript file with library was loaded.

So it's not jQuery best practise, it's a javascript best practise.
