Problem: Try blocks don’t work in a callback world.
Proposed solution:
- Implement API: window.callback.getCatch() - which is a callback to the
parent catch block scope.
- Ie. While the try scope is entered, internally the catch handler is
stored as a function (window.callback.activeCatch.push(thisCatch)). When
the try scope is left, that value is popped.
- Promise: defaults its catch callback to whatever getCatch() returns
I'm sure there are plenty more details that could be covered and "Callback
API" and "getCatch" are totally open to debate. But I hope you get the gist
of it efficiently with this email.
