Async/Await Syntax

What feature does this code demonstrate?

async function* generateNumbers() {
  for (let i = 0; i < 3; i++) {
    await new Promise(r => setTimeout(r, 1000));
    yield i;
  }
}

for await (const num of generateNumbers()) {
  console.log(num);
}

Regular async functions
Promise chaining
Async iterators and generators
This demonstrates async iterators and generators: 1) async function* creates an async generator, 2) yield produces values asynchronously, 3) for await...of enables async iteration, 4) Combines generator functionality with async operations, 5) Useful for streaming data or paginated API calls, 6) Provides clean syntax for working with asynchronous sequences.
