Polyglot done right with GraalVM

Conference
Programming Languages

GraalVM offers a polyglot runtime where you can mix JVM languages with JavaScript, Python, Ruby, R, Webassembly, and so on without the performance penalty for langauge changes. It allows us to write applications that take the best from the respective language ecosystems, machine learning, data science. However, to adequately implement the polyglot application you need to know some GraalVM details: API, concurrency models for different langauges, interopability patterns, and so on. 

In this session we'll go through the necessary minimum amount of information needed for writing good polyglot apps on GraalVM. Currently there are a few companies use GraalVM in production to mix Java (and Scala) with JavaScript and R. Learn how GraalVM helps creating polyglot applications and when you should use it.
