javascript - How to convert Map to array of object?

Question

i'm trying to convert a Map into array of object

Lets say I have the following map:

let myMap = new Map().set('a', 1).set('b', 2);

And I want to convert the above map into the following:

[
   {
      "name": "a",
      "value": "1",
   },
   {
      "name": "b",
      "value": "2",
   }
]

Answer 1

You could take Array.from and map the key/value pairs.

let map = new Map().set('a', 1).set('b', 2),
    array = Array.from(map, ([name, value]) => ({ name, value }));

console.log(array);
