Summary
Although we can think that it is very difficult to use a new programming language, Kotlin is the simplest and interoperable programming language created by the JetBrains team and covers the needs of insufficient Java. Because Android Studio is also based on JetBrains, it is easy to integrate into this IDE and
Kotlin Native introduces Objective-C interoperability and WebAssembly support

Of course, you can easily rewrite these functions, but in most cases it is sufficient to simply declare the class and its properties.That's exactly what we mean when we say Kotlin concise.2. AvoidNullPointerExceptionNow we want to remind you of the greatest pain in many programming languages-null pointer exceptions. We can hardly imagine how many developers have been exposed to null pointers since Tony Holl invented it in 1965, while trying to make things easier.Sadly, we can't co
