Bite-sized knowledge.
Quick, fun coding challenges from the Kodeco team.
Perfect for your coffee break.
Kodebits Day 14: runCatching Fallback
Capture failures as values with runCatching and recover cleanly.
Kodebits Day 13: Associated Types
Associated types let protocols model flexible value containers.
Kodebits Day 12: Null-aware Operators
Combine safe access and fallback defaults in Dart.
Kodebits Day 11: Data Class Copy
Use copy() to derive immutable variants in Kotlin.
Kodebits Day 10: Protocol Extension
Default behavior from protocol extensions keeps code small and reusable.
Kodebits Day 9: Collection If
Build a Dart list dynamically with collection-if.
Kodebits Day 8: Result Mapping
Transform a successful Result value using map.
Kodebits Day 7: Null-safe Length
Use Kotlin null safety and the Elvis operator in one small function.
Kodebits Day 6: Guard Optionals
Practice unwrapping optionals safely with guard.
Kodebits Day 5: Closure Capturing
Values are captured by reference in closures by default in Swift.
Kodebits Day 4: Cascade Notation
Cascades (..) allow you to make a sequence of operations on the same object.
Kodebits Day 3: Null Safety
Kotlin’s null safety features help avoid NullPointerExceptions.
Kodebits Day 2: Property Wrappers
Understand how property wrappers encapsulate storage logic.
Kodebits Day 1: Optional Chaining
Test your knowledge of Swift’s optional chaining and nil coalescing operators.
