Setup

Example

Passing values

Problem: Promises resolve only with a single value. If you want to pass on the result of PromiseCall1 to PromiseCall2, you have different options:

Nesting

You can nest a .then() for Promise Call 2 and return both value from the scope.

Nesting makes it harder to read and should be avoided
