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

Question

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?

Answer 1

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])
