js 将["74","69","65","6c","69","00","00","00","00","00"]转成tieli

在JavaScript中，可以使用String.fromCharCode()方法将Unicode编码转换为对应的字符。对于给定的数组["74","69","65","6c","69","00","00","00","00","00"]，可以通过遍历数组，将每个元素转换为对应的Unicode编码，然后使用String.fromCharCode()方法将Unicode编码转换为字符，并将这些字符拼接起来，即可得到"tieli"。

以下是实现该转换的代码示例：

const arr = ["74","69","65","6c","69","00","00","00","00","00"];
let result = "";

for (let i = 0; i < arr.length; i++) {
  const unicode = parseInt(arr[i], 16); // 将16进制字符串转换为十进制数值
  const char = String.fromCharCode(unicode); // 将Unicode编码转换为字符
  result += char;
}

console.log(result); // 输出 "tieli"
