Common pitfalls when using await in loops include sequential execution bottlenecks and mishandling promises in map(). Sequential for...of loops block execution, while Promise.all() enables parallel execution but fails fast on any rejection. Promise.allSettled() provides safer batch processing by handling both successes and failures. For controlled concurrency respecting API limits, throttling utilities like p-limit offer a middle ground. The forEach() method should never be used with async/await as it doesn't wait for promises to resolve.
