Two tiny functions that make your async code production-ready: `retry` and `timeout`
The article discusses two higher-order functions, `retry` and `timeout`, that enhance the resilience of asynchronous code. These functions allow developers to handle failures and timeouts without modifying the original async functions. By implementing these functions, developers can ensure their code is more robust in production environments.
- ▪The `retry` function automatically reattempts an async operation a specified number of times on failure.
- ▪The `timeout` function allows developers to set a deadline for async operations, rejecting them if they exceed the specified time.
- ▪Both functions maintain the original function's signature, making them easy to integrate into existing code.

In production, none of those assumptions hold forever. Here are two higher-order functions — each under 15 lines — that make any async function resilient without touching its internals. The problem You have an async function.
