Does axios have built-in retry logic? If so, where?

Based on the repository data, axios does not have built-in retry logic in the core library. However, the migration guide demonstrates how to implement retry logic yourself using response interceptors.

The example in [MIGRATION_GUIDE.md:L604-L642] shows a createRetryInterceptor function that you can create to add retry capabilities to your axios instance. This is a user-implemented pattern, not a built-in feature.

The interceptor example demonstrates:

• Tracking retry count on the request config
• Exponential backoff using Math.pow(2, config.__retryCount - 1)
• Re-executing the request using axios(config) after the delay

Here's how it works:

const api = axios.create();
createRetryInterceptor(3, 1000); // 3 max retries, 1000ms initial delay
api.get('/api/data', { retry: true });

So while axios provides the building blocks (interceptors, request/response handling), implementing retry logic is the responsibility of the developer. The architecture supports this well through the interceptor system described in [lib/core/Axios.js:L1-L261], which chains request and response interceptors together.
