NodeJs — Asynchronous Programming with Promises and Async/Await

Node.js is asynchronous by default. Understanding Promises and async/await is essential for writing clean, non-blocking code while handling asynchronous operations like database queries or API requests.

function fetchData() {
  return new Promise((resolve) => {
    setTimeout(() => resolve('Data fetched!'), 1000);
  });
}

async function getData() {
  const data = await fetchData();
  console.log(data);
}

getData();
