0 points
In this article, we would like to show you how to convert a Map to an array of objects in JavaScript.
Quick solution:
xxxxxxxxxx1
const arrayFromMap = Array.from(myMap, ([key, value]) => ({ key, value }));
In this example, we use the Array.from() method to map the key/value pairs from the Map object into an array.
xxxxxxxxxx1
const myMap = new Map([2
[1, 'A'],3
[2, 'B'],4
[3, 'C'],5
]);6

const myArray = Array.from(myMap, ([key, value]) => ({ key, value }));8

console.log(JSON.stringify(myArray, null, 4));Output:
xxxxxxxxxx1
[2
{ key: 1, value: 'A' },3
{ key: 2, value: 'B' },4
{ key: 3, value: 'C' }5
