Converting String to Hexadecimal and Vice Versa

1. String to Hexadecimal: The Magic Unveiled

JavaScript offers a simple way to convert a string to its hexadecimal representation using the Buffer object.

// Example: Converting hexadecimal back to string
const originalHexString = '48656c6c6f2c2048657821'; // Hexadecimal representation
const convertedString = Buffer.from(originalHexString, 'hex').toString('utf-8');
console.log(convertedString);
