Answer 1

const date=[
 {name:"张三",sex:"男",id:1},
 {name:"李四",sex:"女",id:2},
 {name:"王五",sex:"男",id:3},
 {name:"我家哥哥",sex:"女",id:4},
 ];
const data = [
 {name:"小李",sex:"男",id:5},
 {name:"小明",sex:"男",id:6},
 {name:"小黄",sex:"男",id:7},
 {name:"我家哥哥",sex:"女",id:4},
];
let r=date.concat(data);
r=r.filter(e1=>!r.some(e2=>e1!==e2 && e1.name===e2.name && e1.sex===e2.sex && e1.id===e2.id));
console.log(r);
