What does Erlang do that is so special? It has one mechanism for handling concurrency: processes. It creates lightweight processes that are not mapped to OS processes and your application communicates between processes using messages. Within a process there is no locking or any of the other complexities associated with threaded programming. Your data structures don't need locks. You don't have to worry if someone is scribbling over your memory. You write clear simple code.
