How does error propagation work in a Promise chain?
- Propagates to the nearest catch block
- Propagates to the outermost catch block
- Propagates to the nearest then block
- Propagates to the global error handler
In a Promise chain, errors propagate to the nearest catch block. If there isn't a catch block in the immediate chain, it continues to propagate outward until it finds one. This behavior allows for more granular error handling based on where the error occurs in the chain.
