What is the difference between javascript window and jquery $(window)?
I tried in the Chrome console and I get this:
So, I would conclude is "just" a window object wrapped in a jquery object in a way that then I can use jquery's functions on it (like height(), width(), etc...)
I did try googling, and stackoverlowing :) OFC, but to no luck.

Definition of jQuery window. jQuery window object represents an open window in the browser. The window object is automatically created by the browser. Suppose our documents contain multiple frames, then the browser creates one window object for the HTML document and creates additional window objects for each frame.
The $() function The dollar function, $(), can be used as shorthand for the getElementById function. To refer to an element in the Document Object Model (DOM) of an HTML page, the usual function identifying an element is: document.
$(this) is a jQuery wrapper around that element that enables usage of jQuery methods. jQuery calls the callback using apply() to bind this . Calling jQuery a second time (which is a mistake) on the result of $(this) returns an new jQuery object based on the same selector as the first one.
When you write $(window), you should know that that piece of code is going to run on the JS engine. Have you ever wondered why jQuery objects all have parentheses around them? It is because $ is a function object. Basically you're calling the $ function, and passing the native global, or window object to it as an argument.
If you browse through the jQuery source code, you'll see that it'll pass that object on to many internal functions and in the end, it'll return a jQuery wrapper object.
So yes, your assumptions are pretty much correct.
