let johnB = { name: "John Boy" },
lilyA = { name: "Lily Allen" },
peterD = { name: "Peter Drucker" };
const users = new Map([
[johnB, 'boudler'],
[lilyA, 'rock'],
[peterD, 'stone']
])
const obj = {};
users.forEach((value, key) => obj[key].name = value)
console.log(obj)The above doesn't work but it shows the basic intent. I want to get name property from the map keys to be the key when the Map is "converted" to an object. Accessing just the key(without .name), javascript stringifies the object so you end up with [object, Object] as the key.
…an Object that has an object as its keys?
That does not exist. An object property cannot have an object as the key, it must be a string or a symbol. What are you attempting to achieve is simply not possible. Keep using the Map - that's what it is meant to be used for.
I think you just have your logic wrong in your foreach loop.. Is this what you were expecting?
