这是一个使用object-scan更灵活的解决方案。

权衡是它需要依赖。如果这是可以接受的，实际上取决于您的要求是什么以及您可能正在进行的其他数据处理。

// const objectScan = require('object-scan');

const myData = [{ name: 'Pacinciriaidisiasi 55', description: 'Pancirica', userId: 2, trainerId: 60, dateFrom: '2021-01-15T07:00:00', dateTo: '2021-01-15T07:22:00', duration: 0, difficulty: 2, completedPercentage: 0, completed: false, work: 0, activityType: 4, goal: 2, trainingExercises: [] }, { name: 'Hirosima', description: 'hiorsima', difficulty: 2, completedPercentage: 0, completed: false, work: 0, activityType: 4, goal: 3, trainingExercises: { exerciseName: 'Gajo Haj', exerciseId: 76, id: 330, isTimed: false, exercise: { name: 'Gajo Haj', description: 'Gajo jo opis', difficulty: 0, difficulties: [2], equipmentId: 0, mainPictureUrl: '', location: [5], isTest: false, isFunctional: true, isTimed: true, trainingTemplateExercises: [{ trainingTemplateId: 48, exerciseId: 76, series: [34], seriesLoad: [0], seriesPause: [0], seriesCompleted: [false], seriesNote: [''], numberOfWarmupSeries: 0, completed: false, load: 0, failureSet: false, isWarmup: false, isTimed: false, isTest: false, trainingTemplate: { name: 'test', description: 'te', trainerId: 60, activityType: 4, goal: 3, trainingTemplateExercises: [{ trainingTemplateId: 48, exerciseId: 31, series: [36, 51], seriesLoad: [23, 39], seriesPause: [18, 31], seriesCompleted: [false, false], seriesNote: ['radi editovano', 'radi editovano'], numberOfWarmupSeries: 0, completed: false, isTest: false, exercise: { name: 'Potisk s prsi poševno editovani prao 30 dec', description: 'KOntrolirana izvedba.
