Explains worker_threads with new Worker, message passing and offloading CPU work (not I/O). Details ESM: Node removes experimental flag, package.json "type":"module" treats .js as ESM, imports require extensions, loaders and dual-package support are upcoming. Finishes with concrete JS oddities like 0.1+0.2 and -0 versus +0 and instanceof pitfalls.
