function groupBy(arr, prop) {
const map = new Map(Array.from(arr, obj => [obj[prop], []]));
arr.forEach(obj => map.get(obj[prop]).push(obj));
return Array.from(map.values());
}
const data = [{ name: "Display", group: "Technical detals", id: 60, value: 4 }, { name: "Manufacturer", group: "Manufacturer", id: 58, value: "Apple" }, { name: "OS", group: "Technical detals", id: 37, value: "Apple iOS" }];
