Node.js: Faster, Higher, Stronger with GraalVM
summary
GraalVM is introduced as an alternative runtime that includes a Node.js implementation replacing V8 with a Java-written JS engine. The talk explains GraalVM’s multi-language approach (Java, Python, Ruby, R, LLVM/C++), its partial evaluation and Graal JIT techniques for good dynamic-language performance, integration between Node’s event-driven model and the JVM’s threads, sandboxing to restrict filesystem/network access, handling of native JS extensions, and the trade-offs of using this Node.js runtime versus sticking with V8.
