Code Examples for Functional Programming in Node.js

Functional Programming in Node.js — working example

// Functional Programming in Node.js
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));

Functional Programming in Node.js: find user 2, then list names. Say both prints.
