JavaScript展开运算符（Spread Operator）详解：数组操作与对象去重实战

    const arr = [1,2,3,4,5]
    // 我们使用...展开数组
    console.log(...arr) //1 2 3 4 5

    const arr = [1,2,3,4,5]
    //...arr 等价于 1,2,3,4,5
    console.log(Math.max(...arr)) // 5

    const arr = [1,2,3,4,5]
    //...arr 等价于 1,2,3,4,5
    console.log(Math.min(...arr)) // 1

    const arr1 = [1,2,3]
    const arr2 = [4,5,6]
    const arr = [...arr1,...arr2]
    console.log(arr) //[1, 2, 3, 4, 5, 6]

let arr = [
  {id: 1, name: '张三'},
  {id: 2, name: '李四'},
  {id: 1, name: '张三'},
  {id: 3, name: '王五'}
];

let uniqueArr = [...new Set([...arr])];

console.log(uniqueArr);
// 输出: [{id: 1, name: '张三'}, {id: 2, name: '李四'}, {id: 3, name: '王五'}]
