该篇文章介绍了如何使用JavaScript的Set数据结构对给定的员工信息数组进行去重操作，以JSON对象形式存储，便于处理和分析。

let jsonData = [
  {"name": "John", "age": 30, "department": "Sales"},
  {"name": "Alice", "age": 25, "department": "Marketing"},
  {"name": "John", "age": 30, "department": "Sales"},
  {"name": "Bob", "age": 35, "department": "IT"},
  {"name": "Alice", "age": 25, "department": "Marketing"},
  {"name": "Eva", "age": 28, "department": "HR"}
];

// 使用 Set 数据结构进行去重
let uniqueData = Array.from(new Set(jsonData.map(JSON.stringify))).map(JSON.parse);

console.log(uniqueData);
