In the old times, way back, Java used to be the only
JVM language. Later on, a few other players entered the field,
such as Jython and JRuby. But those were just for scripting,
right? It didn't take long for compiled languages to catch
up. With Scala and Kotlin, we have definitely entered the age
of polyglot programming on the JVM. The Truffle project – part
of GraalVM – is a promising approach to make it easy,
efficient, and seamless to run alternative languages on the
same VM as Java. This talk will look at the new age of
polyglot programming and all the cool things we can do with
it.
