Promise链式超时实现：Steve Sanderson在NDC大会的Fetch API方案

Hey there!

The native Promise API doesn’t come with a built-in chainable timeout option, but Steve Sanderson demonstrated a super elegant chainable timeout workaround for the Fetch API during an NDC conference talk (around the 15 minute 31 second mark).

What makes this solution stand out is a really useful detail: even if the timeout triggers, your resolve handler will still complete its execution. For example, if you’re handling response caching, the response will still get stored in your cache just like it would without a timeout.

The talk includes a live demo showing this behavior in action, making it easy to see how the solution works in practice.
