Fell in love with Scala

I was a hard core JAVA developer in both my professional and learning journey, but recently for a reason i have started working with Scala and fell in love with it for the following so far.

1. Semicolons - In Scala its not mandatory to have semicolons at end of the line
2. Variable declarations - Scala allows you to decide whether a variable is immutable (read-only) or not (readwrite) when you declare itself.
3. Ranges - Sometimes we need a sequence of numbers from some start to finish, atleast for testing
4. Future - It avoid lots of boilerplate code I use to write in JAVA when deal with Threads
5. Scala capability of inferring data information
6. Tuple Literals - How many times have you wanted to return two or more values from a method in JAVA?, this can be easily done with Tuple Literals without creating some structural class
7. Option,Some and None - for avoiding nulls, which makes our code ugly in JAVA
8. Sealed Classes - restricts creating sub classes for critical use cases  
9. Scala for comprehensions - Makes our code small, maintainable and more readable
10. Lazy val - for avoiding init static methods
