JavaScript event.currentTarget against this

Question

Is there any difference between event.currentTargetand this? What about performance?

Answer 1

The event attribute currentTargetreturns the element whose event listeners raised the event. This is especially useful for trapping and blistering.

You can also use a keyword this, but when using the Microsoft event logging model, the keyword thisdoes not reference an HTML element.
