 ## jQuery Deferreds
 
-Deferreds were added as a part of a large rewrite of the ajax module, led by Julian Aubourg following the CommonJS Promises/A design. Whilst 1.5 and above include deferred capabilities, former versions of jQuery had `jQuery.ajax()` accept callbacks that would be invoked upon completion or error of the request, but suffered from heavy coupling — the same principle that would drive developers using other languages or toolkits to opt for deferred execution.

 In practice what jQuery's version provides you with are several enhancements to the way callbacks are managed, giving you significantly more flexible ways to provide callbacks that can be invoked whether the original callback dispatch has already fired or not. It is also worth noting that jQuery's Deferred object supports having multiple callbacks bound to the outcome of particular tasks (and not just one) where the task itself can either be synchronous or asynchronous.

 The two main pros of event delegation over binding directly to an element (or set of elements) are performance and the aforementioned event bubbling. Imagine having a large table of 1,000 cells and binding to an event for each cell. That's 1,000 separate event handlers that the browser has to attach, even if they're all mapped to the same function. Instead of binding to each individual cell though, we could instead use delegation to listen for events that occur on the parent table and react accordingly. One event would be bound instead of 1,000, resulting in way better performance and memory management.
 
-The event bubbling that occurs affords us the ability to add cells via AJAX for example, without having to bind events directly to those cells since the parent table is listening for clicks and is therefore notified of clicks on its children. If we weren't using delegation, we'd have to constantly bind events for every cell that's added which is not only a performance issue, but could also become a maintenance nightmare.

 ## The event object
@@ -129,7 +129,7 @@ In this slightly different example, we're defining a function called `sayHello`
 
 But what about that `event` argument in the `sayHello` function — what is it and why does it matter? In all DOM event callbacks, jQuery passes an *event object* argument which contains information about the event, such as precisely when and where it occurred, what type of event it was, which element the event occurred on, and a plethora of other information. Of course you don't have to call it `event`; you could call it `e` or whatever you want to, but `event` is a pretty common convention.
 
-If the element has default functionality for a specific event (like a link opens a new page, a button in a form submits the form, etc.), that default functionality can be cancelled. This is often useful for AJAX requests. When a user clicks on a button to submit a form via AJAX, we'd want to cancel the button/form's default action (to submit it to the form's `action` attribute), and we would instead do an AJAX request to accomplish the same task for a more seamless experience. To do this, we would utilize the event object and call its `.preventDefault()` method. We can also prevent the event from bubbling up the DOM tree using `.stopPropagation()` so that parent elements aren't notified of its occurrence (in the case that event delegation is being used).
