为什么即使输入在数组中，我的array.includes（）也不返回真值？

Question

我想制作一个二维对象数组，并累积存储用户输入的学生信息。然后，此代码的另一个方面是用户可以搜索名称，信息将从数组中获取并显示。第二部分对我不起作用。

var name, section, gender, age, faveSubj1, faveSubj2, faveSubj3;
var studRec = [];

function saveButton() {
  var tempBin = [];
  tempBin.section = document.getElementById("section").value;
  tempBin.age = document.getElementById("age").value;
  tempBin.gender = document.getElementById("gender").value;
  tempBin.faveSubj1 = document.getElementsByClassName("faveSubj")[0].value;
  tempBin.faveSubj2 = document.getElementsByClassName("faveS	ubj")[1].value;
  tempBin.faveSubj3 = document.getElementsByClassName("faveSubj")[2].value;
  var name = document.getElementById("name").value;
  studRec[name] = tempBin;
  console.log(studRec);
  document.getElementById("form").reset();
}

function studFind() {
  var nameSearched = document.getElementById("nameSearch").value;
  var determiner = studRec.includes(nameSearched);
  if (determiner == true) {
    console.log(studRec[nameSearched]);
  } else document.getElementById("result").innerHTML = "The name is not in the database!";
}

<form name="saveStud" method="POST" id="form">
