functions. Because nothing blocks, Node can be given to less-than-export
programmers to build servers.
Furthermore, users of Node are free from worries of dead-locking the

I/O, so the processes never blocks. Because nothing blocks, less-than-expert

But Node takes the mode event-based API further.
In other systems, there is always a blocking call to start the event-loop.
Typically one sets up behavior through callbacks and at the end starts the
server through a call like <code>EventMachine::run()</code>. In Node,
there is no such thing. By default Node enters the event loop after
Node takes the event model a bit further. For example, in other systems
there is always a blocking call to start the event-loop. Typically one
defines behavior through callbacks at the beginning of a script and at the
end starts a server through a call like <code>EventMachine::run()</code>.
In Node, it works differently. By default Node enters the event loop after
executing the input script. Node exits the event loop when there are no more
callbacks to perform.
<p>Node's HTTP API has grown out of my difficulties developing
