The document discusses the rise of JVM ecosystem languages and their increasing popularity, highlighting modern programming paradigms, dynamic and functional programming languages, and successful real-life architectures. It outlines key features of prominent JVM languages such as Groovy, Scala, and Kotlin, emphasizing their benefits like access to Java EE technologies and extensive libraries. The future roadmap for JVM advancements is also briefly covered, showcasing ongoing developments in the platform.
JVM ecosystem languages and the future of JVM
- 1. JVM Ecosystem Languages and The Future of JVM Sazzadur Rahaman Engineer Kona Software Lab. Mizanur Rahman Khan Engineer Kona Software Lab.
- 2. Outline - Rise of Modern Programming Paradigms - Time to make Hands Dirty - JVM Language Profiles - Why JVM Languages are Growingly Popular - Polyglot Programming in JVM - Some Successful Real Life Architectures - Roadmap of JVM
- 3. Rise of Dynamic Typed Languages - Dynamic Typing - Simplicity of Usage - Rich Built in Data Structures - Automatic Memory Management Pioneered, Rapid Application Development
- 4. Rise of Functional Programming Languages - Concurrency and Parallelism inherently - Succinct, Concise, Understandable - Modularity
- 5. Time to Make Hands Dirty
- 6. Pure Functions functions without side effect
- 7. Curried Functions - f(x,y) = x + y - f(1,y) = 1 + y = g(y) - So, g(2) = 1 + 2 - And, g(3) = 1 + 3
- 9. Tail Recursion No stack overflow
- 11. groovy JRuby Jython Scala Clojure Kotlin
- 12. Groovy - Created by James Strachan, around 2003 - Strong, Supports both Static and Dynamic Typing - more compact, less verbose - Inspired by Python, Ruby, Perl, and Smalltalk.
- 13. Scala - Designed By Martin Odersky around 2001 - Designed to be a better java, Yet built on top of java - Non-unified type system (primitives vs. objects) - Functional Meets OOP - Type Inference, Anonymous Functions
- 14. Why JVM Languages are growingly popular - Access to Java EE technologies, those are scalable, very stable, secured, proven in decades - Largest developer community - Jvm code optimization - Native threads - Access to extensive java libraries(library, dev tool, ops tool) - Just in Time Compiler - Remeber? “Write once, Run everywhere”
- 15. Polyglot Programming On JVM
- 16. Classical Class
- 17. Classical Class
- 18. Classical Class
- 19. Polyglot Programming On JVM - Load test: Gatling - Build and Automation tool: Gradle - Testing Framework: Spock - ORM: Hibernate
- 21. LinkedIn
- 22. Twitter - initially monolith application with ruby - backfired on massive scale
- 25. Twitter Stack
- 26. Roadmap of JVM - JDK 7 - invokedynamic - new file I/O - JDK 8 - re-organising memory (remove perm gen) - JDK 9 - Hypervisor-aware JVM - Java module system - Co-operative memory page sharing
- 27. Whatever happened with Java, JVM will stay and Rock!!!
- 28. Thank You
