Catalin Jora gave a presentation on WebAssembly (WASM) at the Docker meetup. He began with an introduction to WASM, describing it as a fast, light alternative to containers that compiles code from 40+ languages to run in sandboxed environments. He then discussed WASI, which makes WASM usable by providing file system and network capabilities. The presentation included a demo of WASM integration with Docker Desktop and examples of WASM applications. Catalin also shared resources on WASM and its use in Kubernetes, as well as potential applications of WASM.
