How to sort a ES6 map object with JavaScript?

To sort a ES6 map object with JavaScript, we convert the map to an array, sort that, and then convert the sorted array back into a map.

For instance, we write

const sortedMap = new Map(
  [...map].sort((a, b) => {
    // ...
  })
);

to convert the map to an array with [...map].

Then we call sort with a callback to sort the array.

And then we convert the sorted array back to a map using the Map constructor.
