如何在javascript中将整数数组转换为十六进制字符串,反之亦然

function intArrayToHexString(arr) {
  return arr.map(num => num.toString(16)).join('');
}

const intArray = [10, 20, 30, 40];
const hexString = intArrayToHexString(intArray);
console.log(hexString); // 输出：'0a141e28'

function hexStringToIntArray(hexString) {
  const intArray = [];
  for (let i = 0; i < hexString.length; i += 2) {
    intArray.push(parseInt(hexString.substr(i, 2), 16));
  }
  return intArray;
}

const hexString = '0a141e28';
const intArray = hexStringToIntArray(hexString);
console.log(intArray); // 输出：[10, 20, 30, 40]
