NMP 8-2: NULL in Kotlin

Since we will be dealing with null values more often when creating Fragments, let's learn about null in Kotlin. We will learn about the spirit behind the default non-nullable data types in Kotlin and how to actually allow null values, the safe call operator (?.), Elvis operator (?:), non-null assertion operator (!!), as well as let scope function with regard to safe calls.

If you have mastered these, you may continue to the next video in the playlist.
