Tell us what’s happening:
I have followed the steps in the instructions. I created a for loop to iterate through the updatedCrew array. I included instructions to log the astronauts names. After the loop, I returned the array. The names are not logging to the console. And the error message states “You should use a for loop to iterate through the updated Crew array and log the name of each astronaut”. I have been trying for a week to see what I’m doing wrong.
Your code so far
const squad = [];
const firstAstronaut = {
id: 1,
name: "Andy",
role: "Commander",
isEVAEligible: true,
priority: 3
};
function addCrewMember(crew, astronaut) {
for (let i = 0; i < crew.length; i++) {
if (crew[i].id === astronaut.id) {
console.log("Duplicate ID: " + astronaut.id);
return;
}
}
crew.push(astronaut);
}
addCrewMember(squad, firstAstronaut);
const remainingCrew = [
{ id: 2, name: "Bart", role: "Pilot", isEVAEligible: false, priority: 8 },
{ id: 3, name: "Caroline", role: "Engineer", isEVAEligible: true, priority: 4 },
{ id: 4, name: "Diego", role: "Scientist", isEVAEligible: false, priority: 1 },
{ id: 5, name: "Elise", role: "Medic", isEVAEligible: true, priority: 7 },
{ id: 6, name: "Felix", role: "Navigator", isEVAEligible: true, priority: 6 },
{ id: 7, name: "Gertrude", role: "Communications", isEVAEligible: false, priority: 4 },
{ id: 8, name: "Hank", role: "Mechanic", isEVAEligible: true, priority: 2 },
{ id: 9, name: "Irene", role: "Specialist", isEVAEligible: true, priority: 5 },
{ id: 10, name: "Joan", role: "Technician", isEVAEligible: false, priority: 1 },
];
for (let i = 0; i < remainingCrew.length; i++) {
addCrewMember(squad, remainingCrew[i]);
}
function swapCrewMembers(crew, fromIndex, toIndex) {
if (
fromIndex < 0 ||
toIndex < 0 ||
fromIndex >= crew.length ||
toIndex >= crew.length
) {
console.log("Invalid crew indices");
return;
}
const updatedCrew = crew.slice();
updatedCrew[fromIndex] = updatedCrew.splice(toIndex, 1, updatedCrew[fromIndex])[0];
// User Editable Region
for (updatedCrew.name in updatedCrew){
console.log(`${updatedCrew.name}`);
}
return updatedCrew;
// User Editable Region
}
