Quick study sessions to strengthen memory and retain key concepts.
When does protocols need a refactor?
When the rule is no longer easy to explain, test, or change without surprising nearby code. Refactoring is…
View Card →What production lens matters for protocols?
Assume the simple demo is not enough. Real data volume, partner behavior, and partial failures will pressure the…
View Card →What review lens should you apply to protocols code?
Ask whether the next engineer can see the rule, the data shape, and the likely failure mode quickly.…
View Card →What testing lens fits protocols?
Test the boundary cases and invariants that would silently break if the rule were misunderstood. Good tests preserve…
View Card →What debugging lens helps most with protocols?
Trace one real example, inspect the state changes, and compare them to the rule you intended to implement.…
View Card →Why does OrderOps care about protocols?
Because the codebase now has enough functions, payloads, and team edits that unclear contracts are slowing reviews and…
View Card →What is the best default for protocols?
Choose the simplest shape that keeps the rule explicit, testable, and easy for the next engineer to read.…
View Card →How should you explain protocols in an interview?
Use protocols when the code depends on a capability or method set rather than on one specific implementation.…
View Card →What is the main pitfall around protocols?
Over-coupling to one concrete class makes testing and substitution harder than necessary. Naming the pitfall early helps you…
View Card →What is the core rule behind protocols?
Use protocols when the code depends on a capability or method set rather than on one specific implementation.…
