Find items in arrays

Problem:

Given a team id, find member's information.

const teams = [
  { id: "t1", name: "Team 1", members: ["u1", "u2"] },
  { id: "t2", name: "Team 2", members: ["u1", "u2", "u3"] },
];

const users = [
  { id: "u1", fullName: "Mars", role: "Engineer" },
  { id: "u2", fullName: "Chester", role: "Consultant" },
  { id: "u3", fullName: "Obi", role: "Frontend Developer" },
];

const teamId = "t1";

Solution:

// find team
const selectedTeam = teams.find((team) => team.id === teamId);

// find memebers
const members = selectedTeam.members;

const selectedMembers = [];
for (const member of members) {
  const selectedUser = users.find((user) => user.id === member);
  selectedMembers.push(selectedUser);
}
