Event: currentTarget property

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred and which may be its descendant.

Value

An EventTarget representing the object to which the current event handler is attached.

Examples

Event.currentTarget is interesting to use when attaching the same event handler to several elements. 

function hide(e) {
  e.currentTarget.style.visibility = "hidden";
  console.log(e.currentTarget);
  // When this function is used as an event handler: this === e.currentTarget
}

const ps = document.getElementsByTagName("p");

for (const p of ps) {
  // Hide the clicked <p> element
  p.addEventListener("click", hide, false);
}

document.body.addEventListener("click", hide, false);

// Click around and make paragraphs disappear

Note: The value of event.currentTarget is only available while the event is being handled. If you console.log() the event object, storing it in a variable, and then look for the currentTarget key in the console, its value will be null.
Instead, you should either use console.log(event.currentTarget) to be able to view it in the console or use the debugger statement, which will pause the execution of your code thus showing you the value of event.currentTarget.
