Difference between Promise and Async/Await in Node.js

Difference between Promise and Async/Await (in node js) is simple if you keep it on paper. Meera uses it for fetch a user then marks in an API handler.

Difference between Promise and Async/Await (in node js) on the board: async function + try/catch. Then say what fetch a user then marks looks like after.

Difference between Promise and Async/Await (in node js) exists so Meera can keep fetch a user then marks correct in an API handler.

Use Difference between Promise and Async/Await (in node js) when fetch a user then marks must stay clear. If a simpler Node.js step works, use that instead.

Don’t do this with Difference between Promise and Async/Await (in node js): unhandled rejection. Interviewers spot it in ten seconds.

Place Difference between Promise and Async/Await (in node js) next to nearby Node.js work — async function + try/catch is the link.

Viva for Difference between Promise and Async/Await (in node js): what it is → async function + try/catch → the mistake (unhandled rejection).

Exam tip

Say Difference between Promise and Async/Await (in node js) in one breath, then async function + try/catch, then unhandled rejection.

Example

function wait(ms) {
  return new Promise((resolve) => setTimeout(resolve, ms));
}

(async () => {
  console.log("start");
  await wait(50);
  console.log("done");
})();

Difference between Promise and Async/Await in Node.js — async/await sits on Promises — cleaner than nested callbacks.
