Chain promises without a network

Read first Task 55

`Promise.resolve()` gives you an already-finished promise, which is how you practise the shape of `fetch()` without making a request.

Definition and example

Chain promises without a network is the focus of this lesson. `Promise.resolve()` gives you an already-finished promise, which is how you practise the shape of `fetch()` without making a request. The task asks you to apply that idea in a small example: Task: Chain promises without a network. What does this program print. Before you run the code, predict what should happen. Then Inspect the browser output and the value your code produces and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
