Show HN: QuickBEAM – run JavaScript as supervised Erlang/OTP processes

QuickBEAM just flung open the door and let JavaScript move into Erlang’s famously crash-proof world, and the crowd is split between “this is genius” and “did we summon a demon?” Think of it like running JS inside a safety-net: if it falls, Erlang’s supervision restarts it. Commenters are buzzing that JS can call Elixir functions, send messages, and even get auto-restarted when it crashes—like a babysitter for your scripts.

The loudest reactions? One camp is hyped: reuse existing Node packages in Elixir, finally! Another camp is clutching pearls over security—untrusted code, sandboxing, and whether deeper protections like Linux’s seccomp might arrive. One commenter flat-out called it “cursed or brilliant,” which instantly became the meme of the thread. Others asked brass‑tacks questions: do these JS runtimes have their own inbox? Can the scheduler interrupt them? How does garbage collection work, and are values immutable? Meanwhile, a dev who tried a similar idea dropped a nostalgic yavascript link and cheered the fuller implementation. The vibe: Elixir folks are excited, security folks are alert, and everyone’s ready to play. If you’ve ever wanted JS’s convenience with Erlang’s grown‑up supervision, this is the mashup—and the comments are the party.
