array-to-map

Converting an array into a Map.

const map = arrayToMap([
  { id: 'a', value: 1 },
  { id: 'b', value: 2 },
  { id: 'c', value: 3 },
]);
console.log(map);
/*
{
  {0 => { id: 'a', value: 1 }}
  {1 => { id: 'b', value: 2 }}
  {2 => { id: 'c', value: 3 }}
}
*/

You can decide how the keys are created:

const map = arrayToMap([
  { id: 'a', value: 1 },
  { id: 'b', value: 2 },
  { id: 'c', value: 3 },
], item => item.id);
console.log(map);
/*
{
  {'a' => { id: 'a', value: 1 }}
  {'b' => { id: 'b', value: 2 }}
  {'c' => { id: 'c', value: 3 }}
}
*/
