"Kotlin" lyrics

Imagine a JVM language
With no unnecessary verbosity
Combining strong type checking
With out-of-the box type inference
With Java interoperability
And building with Gradle, Maven, Amper
Well, my friend, that language exists
And it's KOTLIN!

No more null pointer exceptions
With nullable data types
Safe variable access and Elvis operators
Read-only and mutable variables with the almighty var and val
Mutability and immutability of collections!

All for fun and fun for all
In the name of concise code
Come and join the army of KOTLIN!
All for fun and fun for all
Multi-platform and Android
Come and join the army of KOTLIN!

Wouldn't life be easier
With native string templating
Functional programming
And Lambda functions simplified
Smooth operators overloading
And controlled inheritance with sealed class
That's why from bytecode and fire
JetBrains forged KOTLIN!

Conditional expressions tamed by the wisdom of when
Named arguments and their glorious default values
Multi-inheritance and delegation, and the flamboyant data class
Implementing equals, hashCode and toString!

All for fun and fun for all
In the name of concise code
Come and join the army of KOTLIN!
All for fun and fun for all
Multi-platform and Android
Come and join the army of KOTLIN!

Fun main() runBlocking
Launch
Println(""Amazing solo"")
Launch
Println(""Amazing solo harmonies"")

Parallel programming
Made intuitive with coroutines
Unleashing the power of suspending functions
Syntax shortcuts
With infix and extension functions
Paving the way to write your custom DSLs!

All for fun and fun for all
In the name of concise code
Come and join the army of KOTLIN!
All for fun and fun for all
In the name of concise code
Come and join the army of KOTLIN!
All for fun and fun for all
Multi-platform and Android
Come and join the army of KOTLIN!
Come and join the army of KOTLIN!
Come and join the army of KOTLIN!
