Kotlin – Using ?. and ?.let {} to Avoid Null Checks

Date: 2025-04-18

Kotlin's null safety features, like the safe call operator (?.) and the let function, prevent NullPointerExceptions. ?. safely accesses properties of nullable objects, returning null if the object is null.

This results in cleaner, more readable, and less error-prone code.
