It's about (run)time -- Elixir beyond the hype
summary
Elixir runs on the Erlang/OTP runtime and delivers concrete runtime guarantees: pre-emptive scheduling reduces latency variance, processes are ~4KB so a laptop can hold millions (author reports 12 million), messages are deeply copied, and each process has per-process garbage collection so no stop-the-world GCs. Built-in monitors and supervision trees make connection leaks impossible (example: DB pool reclaims connections when a client process dies), Observer/Web-Observer inspects live systems, and code can be reloaded with zero downtime.
