What is the difference between DOMContentLoaded and DOMContentReady?

Question

According to the MDN wiki, DOMContentLoaded will fire when "page's DOM is ready, [although] the referenced stylesheets, images, and subframes may not be done loading."

What about DOMContentReady? Is it just an alias?

Answer 1

I'm making the claim that the event type "DOMContentReady" does not exist in current implementations (meaning, that no current implementation fires such an event type), and that appearances of such a name are merely lapsus memoriae.

The name "DOMContentLoaded" is not easily remembered, and since the jQuery library uses the method .ready() to bind this event type, I guess, some people just mistakenly used the name "DOMContentReady" to refer to the correct name "DOMContentLoaded".
