Working in a Java/Kotlin environment, everyone always handles all null cases when working in Kotlin, but they are frequently overlooked in the Java applications. Many of the Java apps compensate with more levels of catch-all exception handlers targetting unexpected NPEs. The only time we get NPEs in Kotlin is when Kotlin allows them because of the Kotlin/Java interop problem. Working with Javascript/Typescript, we need to rely on linters to enforce safe practices in Javascript.
