5 async/await Mistakes That Slow Down Your JavaScript Code (And How to Fix Them)

async/await looks clean. But it makes it easy to accidentally run things in sequence that should run in parallel — and JavaScript won't warn you.

5 mistakes covered:

2. await inside forEach — doesn't work how you think
3. Promise.all without error fallback
4. Silent missing await — no error, wrong behavior
5. Awaiting a map that returns promises

Each mistake includes a real code example and a fix.
