**字串陣列 Distinct **
const array = ['1','2','1','3'];
const setType = new Set(array); // {'1','2','3'}
const arrayType = Array.from(setType); // ['1','2','3']
**物件陣列 Distinct **
使用Spread syntax
const arrayObjects = [{ id: '1', name: 'barry' }, { id: '3', name: 'collin' }, { id: '1', name: 'allen' }];
const setType = new Set(arrayObjects.map(item => item.id)); // {'1','3'}
const arrayType = [...setType]; // ['1','3']
