Async/Await Promise Chain Broken

1. Missing await on async function call, continuing before completion
2. Promise.all used with dependent operations (order matters)
3. Try/catch removed, unhandled promise rejections
4. Async function syntax broken (async not declared)
5. Return statement missing in async function

Always await async calls: const data = await fetchData(). Use Promise.all for parallel: Promise.all([fetch1, fetch2]). Use .then() chain for sequential. Wrap in try/catch: try { ... } catch(e) { ... }. Verify async function returns Promise.
