How to Create a New JVM Language

Explore the process of creating a new JVM language called DevoxxLang in this comprehensive conference talk. Dive into the intricacies of constructing grammar, semantics, operations, and an interpreter for a programming language. Learn about parsers, simple optimizations, and tackling interoperability challenges with the JVM. Gain insights into type systems, memory management, and concurrency issues faced by programming languages. Discover the tools and knowledge needed to create your own programming language, and understand the inner workings and challenges of existing ones. Follow along as the speaker demonstrates language creation using tools like GRAIL, Truffle, and IntelliJ IDEA, covering topics such as lexing, compiling, mathematical operators, and implementing operations.
