Tests:
Lodash groupBy
const tmp = _.groupBy(GetArray(), x => x.room.name); const tmp2 = _.forEach(tmp, (val, key) => tmp[key] = _.groupBy(tmp[key], x => x.structureType)); tmp2;
Ramda groupBy
R.pipe( R.groupBy(x => x.room.name), R.map(R.groupBy(x => x.structureType)) )(GetArray());
Hand written
SortMyStructs();
Using Reduce
_.reduce(GetArray(), (acc, x) => { if (!acc.mRooms) acc.mRooms = {}; if (!acc.mRooms[x.room.name]) acc.mRooms[x.room.name] = {mAll: [], mType: {}}; acc.mRooms[x.room.name].mAll.push(x); if (!acc.mRooms[x.room.name].mType[x.structureType]) acc.mRooms[x.room.name].mType[x.structureType] = []; acc.mRooms[x.room.name].mType[x.structureType].push(x); return acc; }, {});
