请用JavaScript实现一个函数，接受一-个IP白名单列表whitelist以及 列表ipList,判断输入的ipList中是否有任何ip包含在whitelist中，如果存在返回true,如果都不存在返回false。要求:1.列出所有测试用例2.定义并实现该函数，有完整出入参*示例:如果有输入:whitelist = ["192.168.1.2"," 192.168.13","192.168.1.4","192.168.1.5"]iplist = ["192.168.1.5,"192.168.1.6"]则函数期望输出为; true

自己测试下写的

let A = ["192.168.1.2", " 192.168.13", "192.168.1.4", "192.168.1.5"],B = ["192.168.1.9", " 192.168.18"]function getIt(whitelist, iplist) {let exp = whitelist.find(item => iplist.includes(item))if (typeof (exp) == "undefined") {return false}else{return true}}
console.log(getIt(A,B));

因为涉及到一个数组中是否包含另一个数组的值和如何判断undefind，遂记录一下
