The post discusses the recent support for WebAssembly (WASM) introduced in GraalVM version 25, which allows Clojure to be run in a WebAssembly environment. Comments from users highlight the technical prowess of GraalVM, noting its high output binary size of 5.6MB for a simple program, which can be reduced using the wasm-opt tool to optimize performance. The compressed output can reach around 2.5MB, making it a practical solution for web applications. User experiences indicate intrigue and confidence in GraalVM's capabilities for specific applications, suggesting a growing interest in integrated environments combining different programming languages and platforms.
