Why setTimeout is Lying to Your Retry Logic
📰 Dev.to · Arnav Gupta
Learn how setTimeout can deceive your retry logic and how to fix it with a simple async/await pattern
Action Steps
- Write a simple retry function using async/await
- Use setTimeout to introduce a delay between retries
- Test the function with a failing operation to see how setTimeout affects the retry logic
- Apply a fix using a more accurate timing mechanism, such as Date.now()
- Compare the results with and without the fix to see the improvement in retry logic accuracy
Who Needs to Know This
Developers and DevOps engineers who implement retry logic in their applications will benefit from understanding this concept to improve the reliability of their systems
