2. Hi. I am Milda
3. Introduction GraalVM allows you to write polyglot applications with a seamless way to pass values from one language to another. With GraalVM there is no copying or marshalling necessary as it is with other polyglot systems. This lets you achieve high performance when language boundaries are crossed. Most of the time there is no additional cost for crossing a language boundary at all.

19. Performance?
20. The goal is similar level of performance as Java has
21. Competitive performance
22. Let’s try it!
23. The downsides Not so seamless Maintenance Javascript, not NodeJS
24. Valid use-cases Very specific tasks Migrating code from one language to another Reusing libraries
25. So?
