const data = [
  { category: 'A', value: 1 },
  { category: 'B', value: 2 },
  { category: 'A', value: 3 },
  { category: 'C', value: 4 },
];

// Using reduce to group objects by a property
const groupedData = data.reduce((accumulator, currentItem) => {
  const category = currentItem.category;
  if (!accumulator[category]) {
    accumulator[category] = [];
  }
  accumulator[category].push(currentItem);
  return accumulator;
}, {});

console.log(groupedData);
// Output: { A: [ { category: 'A', value: 1 }, { category: 'A', value: 3 } ],
//           B: [ { category: 'B', value: 2 } ],
//           C: [ { category: 'C', value: 4 } ] }
