即使在javascript中使用BigInt()之后，也会得到二进制到十进制的错误结果

const binaryString = "110010";
const decimalNumber = parseInt(binaryString, 2);
console.log(decimalNumber); // 输出50

function binaryToDecimal(binaryString) {
  let decimalNumber = 0;
  const length = binaryString.length;

  for (let i = 0; i < length; i++) {
    const bit = parseInt(binaryString[length - 1 - i]);
    decimalNumber += bit * Math.pow(2, i);
  }

  return decimalNumber;
}

const binaryString = "110010";
const decimalNumber = binaryToDecimal(binaryString);
console.log(decimalNumber); // 输出50
