let stu ={
      "sid":1,"sname":"张一","sgender":"男",scores:[
    {
     "mname":"语文",score:80},
    {
     "mname":"数学",score:98},
    {
     "mname":"英语",score:79}
]};
console.log(stu.sid,stu.sname,stu.sgender);
let stus = [
    {
      "sid":1,"sname":"张一","sgender":"男"},
    {
      "sid":2,"sname":"张二","sgender":"男"},
    {
      "sid":3,"sname":"张三","sgender":"男"}
];
for(let i=0;i<stus.length;i++){
     
    let tmp = stus[i];
    console.log(tmp.sid,tmp.sname,tmp.sgender);
}

结果：
