which version of document.ready is this?

I know there's different ways to do it..that is, make sure the html is loaded before the JS runs. This is the most recent one I've seen.

var main = function(){
  //code goes in here
// this goes at the bottom of the page

Just wondering if it's new, old or something in the middle

  // prior to treehouse
  //I had seen it mostly like this
  //all code in here runs after the document loads

  //w3schools has it as this

//Andrew has us putting the link at the bottom of the index 
//with the link to the js file
//so that the index loads before the js

//from the jQuery basics course index file

<script src="http://code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/app.js" type="text/javascript" charset="utf-8"></script>

I'm sure there's other ways also. Just seems like everyone has a different way of doing stuff, which is fascinating...

:point_right: That's the standard JQuery ready function

I'm not sure what you mean by "version". I think all versions of JQuery have this. Perhaps you are thinking of methods for waiting that don't require JQuery, like the onload event.

:information_source: Your last line can be abbreviated as just this (it does the same thing):


Thanks, I like succinct.

Hello Larson,

It's the same function you're used to. The implementation is just a little different; instead of wrapping the function in the $(document).ready() function like this,

     // code

they instantiate (save) the function in a variable, then pass the variable to it instead. When you think about it, the end result is the same.

Note that the function won't be called up until the


line is reached.

Thanks Daniel, I didn't know the ins and outs of how it worked. I appreciate the explanation.
