Eu tenho esse código, mas preciso retornar funções puras em vez de funções mutáveis. É possível? Talvez usando OOP? Não sei como melhorar isso. Tentei retornar os valores de cada função, mas não obtive sucesso. import { AssetStatusType } from '@domain/interfaces/common' import { BothComponentType, ComponentsType, GroupFiltersType, OperationType, OverviewModelType, PendenciesOverviewType, PendenciesType, StructurePendenciesCount, StructureStatusCount } from '../../types' const updateStatusCount = ( statusCount: StructureStatusCount, status: AssetStatusType ) => { statusCount[status] = (statusCount[status] || 0) + 1 } const updatePendenciesCount = ( pendenciesCount: StructurePendenciesCount, key: AssetStatusType, subKey: OperationType | PendenciesOverviewType ) => { pendenciesCount[key] = pendenciesCount[key] ?? {} pendenciesCount[key][subKey] = (pendenciesCount[key]?.[subKey] || 0) + 1 } const processOverviewPendencies = ( pendencies: PendenciesType[] | null | undefined, pendenciesCount: StructurePendenciesCount, countedIds: Set<string>, id: string ) => { if (pendencies?.length) { for (const { state, pendencyType } of pendencies) { const uniqueId = `${state}-${pendencyType}-${id}` if (!countedIds.has(uniqueId)) { updatePendenciesCount(pendenciesCount, state, pendencyType) countedIds.add(uniqueId) } } } } const processOverviewComponents = ( components: ComponentsType[], isGroupByTree: boolean, statusCount: StructureStatusCount, pendenciesCount: StructurePendenciesCount, countedIds: Set<string>, id: string, type: BothComponentType ) => { for (const { pendencies, status, operationType } of components) { if (isGroupByTree && type === 'location') { updateStatusCount(statusCount, status) if (operationType) { updatePendenciesCount(pendenciesCount, status, operationType) } } processOverviewPendencies(pendencies, pendenciesCount, countedIds, id) } } const processOverviewData = ( data: OverviewModelType[], groupBy: GroupFiltersType, statusCount: StructureStatusCount, pendenciesCount: StructurePendenciesCount, countedIds: Set<string> ) => { const isGroupByTree = groupBy === 'tree' const isGroupByAsset = groupBy === 'asset' for (const { id, status, components, operationType, type } of data) { if (isGroupByAsset || type === 'asset') { updateStatusCount(statusCount, status) if (operationType) { updatePendenciesCount(pendenciesCount, status, operationType) } } processOverviewComponents( components, isGroupByTree, statusCount, pendenciesCount, countedIds, id, type ) } } export const calculateOverviewCounts = ( data: OverviewModelType[], groupBy: GroupFiltersType ) => { const statusCount: StructureStatusCount = {} as StructureStatusCount const pendenciesCount: StructurePendenciesCount = {} as StructurePendenciesCount const countedIds = new Set<string>() processOverviewData(data, groupBy, statusCount, pendenciesCount, countedIds) return { ...statusCount, pendencies: pendenciesCount } } Existe uma maneira mais limpa e elegante de fazer isso? Preciso retornar um objeto como este: // calculateOverviewCounts return this { pendencies: StructurePendenciesCount; working: number; inAlert: number; warning: number; stopped: number; off: number; } StructurePendenciesCount é:
