Promises and Async/Await

A Promise represents a future value. async/await lets you write async code that reads like sync code.

• await pauses an async function until the Promise settles.
• Always handle rejection with try/catch or .catch.
• Promise.all runs independent work in parallel.

async function main() {
  const value = await Promise.resolve("ready");
  console.log(value);
}
main();
