JavaScript Async/Await Patterns

Modern JavaScript async patterns for clean, readable asynchronous code:

Basic Pattern:

async function fetchData() {
  const response = await fetch("/api/data");
  return response.json();
}

Parallel Execution:

const [users, posts] = await Promise.all([
  fetchUsers(),
  fetchPosts()
]);

Error Handling:

try {
  const data = await riskyOperation();
} catch (error) {
  handleError(error);
}

Key Tips: Always handle promise rejections. Use Promise.all for independent operations. Avoid sequential awaits when operations can run in parallel.
