 var {data, timeStamp, target} = midiMessageEvent,
So in your line above data, timeStamp, target are reserved words or created vars for holding the "three attributes?" of object midiMessageEvent which you "extract/read out"? You could had called them ini, mini, moe it is not reserved words?

When you read out these object "attributes?" is the order of importance, or could it as well been.

var {target, timeStamp, data} = midiMessageEvent

is midiMessageEvent an event or an object "i can see it says event but...", i think the language of Javascript start to get overpopulated with unnecessary lingo that do not directly help.
