Reduce array of objects into object [duplicate]

Answer 1

Something like this should work:

const data = [
  { name: 'foo', type: 'fizz', val: 9 },
  { name: 'boo', type: 'buzz', val: 3 },
  { name: 'bar', type: 'fizz', val: 4 },
  { name: 'car', type: 'buzz', val: 7 },
];

const reduced = data.reduce((acc, item) => {
  acc[item.val] = item.name;
  return acc;
}, {});

console.log(reduced);
