Identifies the current target for the event, as the event traverses the DOM.
Identifies the current target for the event, as the event traverses the DOM. It always refers to the element the event handler has been attached to as opposed to event.target which identifies the element on which the event occurred.
MDN
Returns a boolean indicating whether or not event.preventDefault() was called on the event.
Returns a boolean indicating whether or not event.preventDefault() was called on the event.

Indicates which phase of the event flow is currently being evaluated.
Indicates which phase of the event flow is currently being evaluated.

Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)

The ProgressEvent.lengthComputable read-only property is a Boolean flag indicating if the resource concerned by the ProgressEvent has a length that can be calculated.
The ProgressEvent.lengthComputable read-only property is a Boolean flag indicating if the resource concerned by the ProgressEvent has a length that can be calculated. If not, the ProgressEvent.total property has no significant value.
MDN
The ProgressEvent.loaded read-only property is an unsigned long long representing the amount of work already performed by the underlying process.
The ProgressEvent.loaded read-only property is an unsigned long long representing the amount of work already performed by the underlying process. The ratio of work done can be calculated with the property and ProgressEvent.total. When downloading a resource using HTTP, this only represent the part of the content itself, not headers and other overhead.
MDN
Cancels the event if it is cancelable, without stopping further propagation of the event.
Cancels the event if it is cancelable, without stopping further propagation of the event.
MDN
For this particular event, no other listener will be called.
For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)
MDN
Stops the propagation of events further along in the DOM.
Stops the propagation of events further along in the DOM.

This property of event objects is the object the event was dispatched on.
This property of event objects is the object the event was dispatched on. It is different than event.currentTarget when the event handler is called in bubbling or capturing phase of the event.
MDN
Returns the time (in milliseconds since the epoch) at which the event was created.
Returns the time (in milliseconds since the epoch) at which the event was created.

The ProgressEvent.total read-only property is an unsigned long long representing the total amount of work that the underlying process is in the progress of performing.
