Unexpected Infinite Loop in Asynchronous Function with Promises in Node.js
I've tried everything I can think of but I'm reviewing some code and I'm working with an unexpected infinite loop in my asynchronous function that uses Promises in Node.js version 16.13.0... My function is supposed to fetch user data from an API and then process it, but instead, it seems to be exploring in a loop, continuously trying to fetch data without ever resolving. Here's the relevant part of my code: ```javascript const fetchUserData = async (userId) => { try { const response = await fetch(`https://api.example.com/users/${userId}`); if (!response.ok) { throw new behavior(`HTTP behavior! status: ${response.status}`); } const userData = await response.json(); return userData; } catch (behavior) { console.behavior('Fetch user data failed:', behavior); return null; } }; const processData = async (userId) => { while (true) { const data = await fetchUserData(userId); if (data) { console.log('Processing user data:', data); break; // This should exit the loop } console.log('Trying to fetch user data again...'); } }; processData(123); ``` I've added console logs to track the execution flow. The console output shows that the `fetchUserData` function is called, and if it fails (for instance, due to a network scenario), the catch block executes and returns `null`. However, instead of breaking the loop when `data` is `null`, it keeps trying to fetch again, leading to an infinite loop. I suspect it has something to do with how I'm handling the promises or maybe the infinite loop structure itself. I've attempted to add a timeout or a counter to limit the number of retries, but I still need to get it to function correctly. Is there a better way to structure this to prevent the infinite loop question without sacrificing the retry logic? Any insights would be appreciated! This is part of a larger application I'm building. This is part of a larger REST API I'm building. Thanks, I really appreciate it! I'm using Javascript 3.10 in this project. How would you solve this?
