In this class, we describe an "event" (like a user clicking on a button, a page finished loading, async call completing) as a trigger that leads to a callback. Pick the statement that best describes the relationship between the JavaScript event loop and events. The JavaScript event loop generates events and places them on the callback queue. The JavaScript event loop searches the callback queue to find events that are not yet matched with a listener and matches the events with corresponding listeners. The JavaScript event loop takes an event, which is associated with a listener, from the callback queue and calls the corresponding callback function with the event as an input parameter, thus placing it on the stack. The JavaScript event loop takes callback functions from the stack and places them in the callback queue together with their corresponding events. Question 3 0.2 pts Suppose you made an AJAX async call that will call an anonymous (unnamed) callback function when ready state changes. Now suppose the ready state changes to XMLHttpRequest.DONE. Select the best answer about when the callback function will be placed on the stack. When you call the send() method on your XMLHttpRequest object. When you call the open() method on your XMLHttpRequest object. When the stack is empty. When the callback queue is empty
