Fungsi Penguraian Sandi 🛠️

function decode(secret, key) {
  let out = ''
  for (let i = 0; i < secret.length; i++) {
    out += String.fromCharCode(secret.charCodeAt(i) - key)
  }
  return out
}
console.log(decode('ecv', 2))

Sandi Dahulu, Uraikan Kemudian 🔄

function shiftAll(msg, k) {
  let out = ''
  for (let i = 0; i < msg.length; i++) out += String.fromCharCode(msg.charCodeAt(i) + k)
  return out
}
let secret = shiftAll('hi', 3)
let back = shiftAll(secret, -3)
console.log('Secret:', secret, 'Back:', back)

Kunci Salah, Pesan Salah ❌
