The ready() method is used to make a function available after the document is loaded. Whatever code you write inside the $(document ). ready() method will run once the page DOM is ready to execute JavaScript code.
$( document ).ready() Code included inside $( window ).on( "load", function() { ... }) will run once the entire page (images or iframes), not just the DOM, is ready. // A $( document ).ready() block. console.log( "ready!" );
The document. ready() function will be executed as soon as the DOM is loaded. It will not wait for the resources like images, scripts, objects, iframes, etc to get loaded.

Where i said:
jQuery document.ready will run your code when the HTML is all ready, but before images and other resources have finished. This is the earliest possible time that you can change the DOM with JavaScript, so it's widely used. In Modern Browsers like google chrome it is replaced by DOMContentLoaded3. Again more info Here.
So by your picture:
$document.ready(fn) will be loaded at the beggining of interactive face when the Dom has "completed" loading...
