Overview

Michael Feathers' GOTO Chicago 2018 talk on reducing error checks and conditional logic in code. He offers a framework for handling errors and decisions at the level of code and architecture.

HN recommends it for the idea of giving data instead of asking for it, and ties it to zero values and exception-free design.

I was watching this the other day: [VIDEO] Unconditional Code by Michael Feathers One solution to this problem is discussed toward the middle: giving data instead of asking for data avoids error conditions.

Please no on the Universal nil. Meaningful zero values for types are essential. It may be confusing to some that nil is a valid zero value for some types and not others, in which case that needs to be refined, but having a type that can either be a value, a zero value, or a nil introduces complexity where there should be simplicity. Having a zero value enables, for example, Unconditional Programming: [VIDEO]
