/* The Yeti approaches the "Gate of Whispered Secrets", an ancient light that guards the entrance to the hidden Crystal Caverns. To unlock the gate, the Yeti must provide the correct passphrases derived from the names of past travelers, hashed with the wisdom of the secret key. Travelers are stored in an array, sorted by latest arrival, but the Yeti needs to iterate over them, starting with the first arrival. With the light failing due to a coding issue, the Yeti must repair the function to properly hash the names and retrieve the passphrases to proceed. */ function* reverseIterator(array) { let index = array.length; while (index > 0) { yield array[--index]; } } function generatePassphraseHash(travelers, secretKey) { return reverseIterator(travelers).map((traveler) => { const readableFullName = traveler.firstName + " " + traveler.lastName; let hash = 0; for (let i = 0; i < readableFullName.length; i++) { hash += readableFullName.charCodeAt(i) * secretKey; } console.log(hash) return hash; }).toArray() }
