Viva for Difference between dependencies, devDependencies and peerDependencies: what it is → one Difference between dependencies, devDependencies and peerDependencies step Ananya can write from memory → the mistake (only reciting the name of Difference between dependencies, devDependencies and peerDependencies).

Exam tip

Say Difference between dependencies, devDependencies and peerDependencies in one breath, then one Difference between dependencies, devDependencies and peerDependencies step Ananya can write from memory, then only reciting the name of Difference between dependencies, devDependencies and peerDependencies.

Example

// Difference between dependencies, devDependencies and peerDependencies
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

Difference between dependencies, devDependencies and peerDependencies: find user 2, then list names. Say both prints.
