How to Create a New JVM Language in Under an Hour

Explore the process of creating a new JVM language in under an hour through this comprehensive Devoxx conference talk. Dive into the construction of a programming language called DevoxxLang, covering grammar, semantics, operations, and interpreter development. Learn about parsers, simple optimizations, and tackling interoperability with the JVM. Gain insights into type systems, memory management, and concurrency issues faced by programming languages. Discover the tools and challenges involved in language creation, enhancing your understanding of how programming languages work. Led by Oleg Šelajev, an experienced engineer and advocate at ZeroTurnaround, this 58-minute session provides a practical guide to language development, complete with discussions on GURL, Truffle implementations, and benchmarking techniques.
