js数组对象去重同时判断两个属性条件相同去重

arr=[

 {
    maxDeptCode: "md3"
    maxDeptName: "泡泡"
    minDeptCode: "md301"
    minDeptName: "泡泡少儿"
    schoolId: 1
    schoolName: "北京"
 },
 {
    maxDeptCode: "md2"
    maxDeptName: "中学"
    minDeptCode: "md201"
    minDeptName: "中学一对一"
    schoolId: 1
    schoolName: "北京"
 },{
    maxDeptCode: "md3"
    maxDeptName: "泡泡"
    minDeptCode: "md301"
    minDeptName: "泡泡少儿"
    schoolId: 1
    schoolName: "北京"
 },
]

function process(arr) {
    // 缓存用于记录
    const cache = [];
    for (const t of arr) {
        // 检查缓存中是否已经存在
        if (cache.find(c => c.maxDeptCode === t.maxDeptCode && c.minDeptCode === t.minDeptCode)) {
            // 已经存在说明以前记录过，现在这个就是多余的，直接忽略
            continue;
        }
        // 不存在就说明以前没遇到过，把它记录下来
        cache.push(t);
    }

    // 记录结果就是过滤后的结果
    return cache;
}
