Many objects in Node emit events: a TCP server emits an event each time there is a connection, a child process emits an event when it exits\. All objects which emit events are are instances of node\.EventEmitter\.
.sp
Events are represented by a snakecased string\. Here are some examples: "connection", "receive", "message_begin"\.

Functions can be then be attached to objects, to be executed when an event is emitted\. These functions are called \fIlisteners\fR\.
