假设以下是带有重复项的对象数组-
var studentDetails=[ {studentId:101}, {studentId:104}, {studentId:106}, {studentId:104}, {studentId:110}, {studentId:106}, ]
使用set的概念来删除重复项,如以下代码所示:
var studentDetails=[ {studentId:101}, {studentId:104}, {studentId:106}, {studentId:104}, {studentId:110}, {studentId:106}, ] const distinctValues = new Set const withoutDuplicate = [] for (const tempObj of studentDetails) { if (!distinctValues.has(tempObj.studentId)) { distinctValues.add(tempObj.studentId) withoutDuplicate.push(tempObj) } } console.log(withoutDuplicate);
要运行上述程序,您需要使用以下命令-
node fileName.js.
输出结果
在这里,我的文件名为demo158.js。这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo158.js [ { studentId: 101 }, { studentId: 104 }, { studentId: 106 }, { studentId: 110 } ]
