const cipher = salt => {

      .map(hex => parseInt(hex, 16))
      .map(applySaltToChar)
      .map(charCode => String.fromCharCode(charCode))
      .join('');
}

// To create a cipher
const myCipher = cipher('mySecretSalt')

//Then cipher any text:
console.log(myCipher('the secret string'))

//To decipher, you need to create a decipher and use it:
const myDecipher = decipher('mySecretSalt')
console.log(myDecipher("7c606d287b6d6b7a6d7c287b7c7a61666f"))
