Solución… 😄 . Por fin se logró... 😅. . Para la realización del reto es importante convertir fechas en String a objetos de fecha Date. Puede realizarse de la siguiente manera: .
// donde 'date' es un string en formato dd/mm new Date(`${date} ${new Date().getFullYear()}`)
. Cuando queremos saber si una habitación no es disponible, debemos recorrer toda la lista de reservas 'reserva actual' y comparar los checkIn y checkOut de estas con los de la reserva que queremos realizar 'reserva'. . Las condiciones son las siguientes: .
export function hotelSystem(rooms) { let roomList = []; // Buscar reserva por id function searchReservation(id) { let foundRoom = roomList.find((room) => room.id === id); if (foundRoom) { return foundRoom; } throw new Error("La reservación no fue encontrada"); } // Ordenar reservas function getSortReservations() { let sortedRooms = [...roomList].sort((a, b) => { let dateA = convertToDate(a.checkIn); let dateB = convertToDate(b.checkIn); return dateA - dateB; }); return sortedRooms; } // Convertir a fechas function convertToDate(date) { return new Date(`${date} ${new Date().getFullYear()}`); } // Agregar reserva function addReservation(reservation) { if (!isAvailable(reservation)) { throw new Error("La habitación no está disponible"); } roomList.push(reservation); return 'Reserva exitosa'; } // Verificar si la habitación está disponible function isAvailable(reservation) { let resIn = reservation.checkIn; let resOut = reservation.checkOut; for (let actRes of roomList) { let actCheckIn = actRes.checkIn; let actCheckOut = actRes.checkIn; if ( (resIn >= actCheckIn && resIn < actCheckOut) || (resOut > actCheckIn && resOut <= actCheckOut) || (resIn <= actCheckIn && resOut >= actCheckOut) ) { if (actRes.roomNumber === reservation.roomNumber) { return false; } } } return true; } // Remover reserva por id function removeReservation(id) { let index = roomList.findIndex((room) => room.id === id); if (index > -1) { return roomList.splice(index, 1)[0]; } else { throw new Error("La reservación que se busca remover no existe"); } } // Retornamos todas las reservas function getReservations() { return roomList; } // Retornar las habitaciones disponibles function getAvailableRooms(checkIn, checkOut) { let availableRooms = []; for (let i = 1; i <= rooms; i++) { let reservation = { checkIn, checkOut, roomNumber: i }; if (isAvailable(reservation)) { availableRooms.push(i); } } return availableRooms; } return { searchReservation, getSortReservations, addReservation, removeReservation, getReservations, getAvailableRooms }; }
Saludos. Tengo una pregunta ¿A alguien mas le pasa que no pueden seguir avanzando mas en desafío? Muchas gracias!!
hola, estoy igual, a partir de este punto no me deja avanzar.

export function hotelSystem(rooms) { let reservations = [] const _rooms = new Array(rooms) for (let i = 0; i < _rooms.length; i++) _rooms[i] = i + 1 const dateToNumber = (date) => { const currentYear = new Date().getFullYear().toString() return new Date(date + '/' + currentYear).getTime() } const occupiedRooms = (checkIn,checkOut) => reservations.filter(r => dateToNumber(checkOut) > dateToNumber(r.checkIn) || dateToNumber(checkIn) < dateToNumber(r.checkOut) ).map(r => r.roomNumber) // Tu código aquí return { searchReservation(id) { const reservation = reservations.find(r => r.id === id) if (!reservation) throw new Error("La reservación no fue encontrada") return reservation }, getSortReservations() { return [...reservations].sort((a, b) => dateToNumber(a.checkIn) - dateToNumber(b.checkIn)) }, addReservation(reservation) { const roomAvailable = !occupiedRooms(reservation.checkIn, reservation.checkOut).includes(reservation.roomNumber) if (!roomAvailable) throw new Error("La habitación no está disponible") reservations.push(reservation) return "La habitación se creo correctamente" }, removeReservation(id) { const reservation = this.searchReservation(id) reservations = reservations.filter(r => r.id !== id) return reservation }, getReservations() { return reservations }, getAvailableRooms(checkIn, checkOut) { return _rooms.filter(room => !(occupiedRooms(checkIn,checkOut).includes(room))) } } }
Probablemente a alguien más le sirva, esto me ayudó a entender un poco cómo organizar las fechas.
Los números del 1 al 30 simulan un mes
Los números rojos (5 al 20) simulan una reserva vieja
Los números verdes simulan una nueva reserva
Como ven, hay 4 casos posibles para la nueva reserva.

Por lo que veo en su mayoría, todos coincidimos en el mismo error al momento de presentar este reto. La verdad estuvo super interesante porque aplicamos muchos conocimientos que hemos visto durante el curso.
Sin embargo, insisto que de tener una mejor documentación en los ejercicios nos ayudaria ahorrar algo de tiempo.
Creo que todos los que han presentado su Challenge saben de que estoy hablando.... algo falto documentar.. en fin fue un reto, pude hacerlo luego de unas horas quemando neuronas 🤣

Saludos. Alguien me podria ayudar? Solo me falta pasar la ultima prueba :
function hotelSystem(rooms) { // Tu código aquí let reservations = []; return { searchReservation: (id) => { const reservation = reservations.find(reservation => reservation.id === id); if (!reservation) { throw new Error("La reservación no fue encontrada"); } return reservation; }, getSortReservations: () => { return [...reservations].sort((a, b) => new Date(a.checkIn) - new Date(b.checkIn)); }, addReservation: (reservation) => { const { checkIn, checkOut, roomNumber } = reservation; const isRoomAvailable = reservations.every(reservation => { const { checkIn: checkInRes, checkOut: checkOutRes } = reservation; return checkIn < checkInRes && checkOut < checkInRes || checkIn > checkOutRes && checkOut > checkOutRes; }); if (!isRoomAvailable) { throw new Error("La habitación no está disponible"); } reservations.push(reservation); return "Reservación agregada exitosamente"; }, removeReservation: (id) => { const reservation = reservations.find(reservation => reservation.id === id); if (!reservation) { throw new Error("La reservación que se busca remover no existe"); } reservations = reservations.filter(reservation => reservation.id !== id); return reservation; }, getReservations: () => reservations, getAvailableRooms: (checkIn, checkOut) => { const availableRooms = []; [...Array(rooms)].forEach((_, index) => { const isRoomAvailable = reservations.every((reservation) => { if (reservation.roomNumber === index + 1) { const { checkIn: checkInRes, checkOut: checkOutRes } = reservation; return checkIn >= checkOutRes || checkOut <= checkInRes; } return true; }); if (isRoomAvailable) { availableRooms.push(index + 1); } }); return availableRooms; }, } }
Los dates de checkOut y checkIn que recibimos en los objetos estan en formato MM/DD?
Están en formato dd/mm :D
Mi solución 💚 💚 💚 💚 💚 💚
function hotelSystem(rooms) { const totalRooms = rooms; const reservations = []; const searchReservation = (id) => { const reservation = reservations.find((reservation) => reservation.id === id) if (reservation === undefined) throw new Error("La reservación no fue encontrada") return reservation } const getSortReservations = () => [...reservations].sort((resA, resB) => { const dateA = new Date(resA.checkIn) const dateB = new Date(resB.checkIn) return dateA - dateB }) const addReservation = (reservation) => { const newCheckIn = new Date(reservation.checkIn) const newCheckOut = new Date(reservation.checkOut) const isReserved = reservations.findIndex((res) => { const actualCheckIn = new Date(res.checkIn) const actualCheckOut = new Date(res.checkOut) return res.roomNumber === reservation.roomNumber && (newCheckIn < actualCheckOut && newCheckOut > actualCheckIn) }) if (isReserved !== -1) throw new Error("La habitación no está disponible") reservations.push(reservation) return 'Reserva exitosa'; } const removeReservation = (id) => { const indexReservation = reservations.findIndex((res) => res.id === id) if (indexReservation === -1) throw new Error("La reservación que se busca remover no existe"); return reservations.splice(indexReservation,1)[0] } const getReservations = () => reservations; const getAvailableRooms = (checkIn, checkOut) => { const dateCheckIn = new Date(checkIn) const dateCheckOut = new Date(checkOut) const availableRooms = Array.from({ length: totalRooms }, (_, i) => i + 1) reservations.forEach((res) => { const actualCheckIn = new Date(res.checkIn) const actualCheckOut = new Date(res.checkOut) if (dateCheckIn <= actualCheckOut && dateCheckOut >= actualCheckIn) { let indexRoom = availableRooms.indexOf(res.roomNumber) if(indexRoom!==-1) availableRooms.splice(indexRoom, 1) } }) return availableRooms } return { searchReservation, getSortReservations, addReservation, removeReservation, getReservations, getAvailableRooms } }
My solution 👇
function hotelSystem(rooms) { const reservations = []; function searchReservation(id) { const index = reservations.findIndex((room) => room.id === id); if (index > -1) { return reservations[index]; } throw new Error("La reservación no existe"); } function getSortReservations() { const copy = [...reservations]; copy.sort((a, b) => { const aDate = new Date(`${a.checkIn} ${new Date().getFullYear()}`); const bDate = new Date(`${b.checkIn} ${new Date().getFullYear()}`); return aDate - bDate; }); return copy; } function addReservation(reservation) { if (!isAvailable(reservation)) { throw new Error("La habitación se encuentra ocupada"); } reservations.push(reservation); return `La reservación de ${reservation.name} fue agendada exitosamente`; } function removeReservation(id) { const index = reservations.findIndex((room) => room.id === id); if (index > -1) { const removedReservation = reservations[index]; reservations.splice(index, 1); return removedReservation; } throw new Error("La habitación que se busca remover no existe"); } function getReservations() { return reservations; } function isAvailable(reservation) { const checkIn = reservation.checkIn; const checkOut = reservation.checkOut; for (const currentReservation of reservations) { const currentCheckIn = currentReservation.checkIn; const currentCheckOut = currentReservation.checkOut; if ( (checkIn >= currentCheckIn && checkIn < currentCheckOut) || (checkOut > currentCheckIn && checkOut <= currentCheckOut) || (checkIn <= currentCheckIn && checkOut >= currentCheckOut) ) { if (currentReservation.roomNumber === reservation.roomNumber) { return false; } } } return true; } function getAvailableRooms(checkIn, checkOut) { const availableRooms = []; for (let i = 1; i <= rooms; i++) { const reservation = { checkIn, checkOut, roomNumber: i }; if (isAvailable(reservation)) { availableRooms.push(i); } } return availableRooms; } return { searchReservation, getSortReservations, addReservation, removeReservation, getReservations, getAvailableRooms, }; }
A continuación, mi solución:
export function hotelSystem(rooms) { let numCuartos = rooms; let reservaciones = new Array(); return { searchReservation(id) { let result = reservaciones.find(reserv => reserv.id == id); if (result == undefined) { throw new Error("La reservación no fue encontrada"); } else { return result; } }, getSortReservations() { let copiaReserv = reservaciones; copiaReserv.sort(function (a, b) { let ac = new Date(a.checkIn); let bc = new Date(b.checkIn); if (ac < bc) { return -1; } else if (ac > bc) { return 1; } else { return 0;} }) return copiaReserv; }, addReservation(reservation) { let comprueba = reservaciones.every(function (item) { if (item.roomNumber == reservation.roomNumber) { let reservIn = new Date(reservation.checkIn); let reservOut = new Date(reservation.checkOut); let itemIn = new Date(item.checkIn); let itemOut = new Date(item.checkOut); //throw new Error(reservIn+reservOut+itemIn+itemOut) if (reservIn > itemOut || reservOut < itemIn) { return true; } else { return false; } } else { return true; } }); if (comprueba) { reservaciones.push(reservation); return ""; } else { throw new Error("La habitación no está disponible") } }, removeReservation(id) { if (reservaciones.findIndex((re) => re.id == id) == -1) { throw new Error("La reservación que se busca remover no existe"); } else { let indice = reservaciones.findIndex((re) => re.id == id); let reserva = reservaciones.find((re) => re.id == id); reservaciones.splice(indice, 1); return reserva; } }, getReservations() { return reservaciones; }, getAvailableRooms(chkIn, chkOut) { let chIn = chkIn.split("/"); chIn.reverse(); chIn = chIn.join("/"); let chOut = chkOut.split("/"); chOut.reverse(); chOut = chOut.join("/"); let ocupadas = reservaciones.filter(function (item) { if (new Date(item.checkOut) < new Date(chIn) || new Date(item.checkIn) > new Date(chOut)) { return false; } else { return true; } }); let habOcu = new Array(); ocupadas.forEach(function (item) { habOcu.push(item.roomNumber); }) let resultado = new Array(); for (let i = 1; i <= rooms; i++) { let comprueba = habOcu.includes(i); if (!comprueba) { resultado.push(i); } } return resultado; } } }

function hotelSystem(rooms) { const reservations = []; return{ searchReservation:(id)=> { const reservation = reservations.find(element => element.id === id); if(reservation) { return reservation; } else { throw new Error('La reservación no fue encontrada'); } }, getSortReservations: ()=>{ const sortedReservations = reservations.sort((a,b) => { if(a.checkIn > b.checkIn) { return 1 } if(a.checkIn < b.checkIn) { return -1 } if(b.checkIn === a.checkIn) { return 0 } }) return sortedReservations; }, addReservation: (reservation) =>{ const noAvailableroom = reservations.some(element => element.roomNumber === reservation.roomNumber && (element.checkIn <= reservation.checkIn || element.checkOut >= reservation.checkOut)) if(!noAvailableroom) { reservations.push(reservation) return 'La habitación ha sido reservada' } else { throw new Error('La habitación no está disponible'); } }, removeReservation: (id) =>{ const idReservation = reservations.findIndex(element => element.id === id); const reservation = reservations.at(idReservation) if(idReservation !==-1) { reservations.splice(idReservation, 1); return reservation; } else { throw new Error('"La reservación que se busca remover no existe"'); } }, getReservations: () =>{ return reservations; }, getAvailableRooms: (checkIn, checkOut) =>{ const availableRooms = []; for (let index = 1; index <= rooms; index++) { const noAvailableroom = reservations.some(element => element.roomNumber === index && (element.checkIn <= checkIn || element.checkOut >= checkOut)) if (!noAvailableroom) { availableRooms.push(index) } } return availableRooms; } } }
