javascript - If a Map has only one member, how to get it without looping if you don't know the key?

Is it true the only way to get value of a Map when it has only one member and you don't know the key is with a looping construct of some kind that iterates the map?

or is there some kind of shorthand myMap.item(0) sort of thing?

To achieve expected result, use below option ES6 spread operator and index of [0][1] without using key

var map = new Map()
map.set('contra', 'Asynchronous flow control')

console.log([...map][0][1])
