convert a number from base 2 to base 16 in typescript

To convert a number from base 2 to base 16 in Typescript, you can follow the following steps:

1. Convert the base 2 number to a decimal number.
2. Convert the decimal number to a base 16 number.

Here's some sample code that demonstrates this:

index.ts
function convertBase2ToBase16(num: string): string {
  const decimalNum = parseInt(num, 2);
  return decimalNum.toString(16).toUpperCase();
}

// Example usage:
console.log(convertBase2ToBase16("101010")); // Output: "2A"
222 chars
8 lines

In this code, we first convert the input number to a decimal number using parseInt. We then convert the decimal number to a base 16 number using the toString method with a radix of 16. Finally, we use toUpperCase to make the output uppercased for consistency.
