.SH DESCRIPTION
|
|
|
|
Node is a set of libraries for javascript which allows
|
|
it to be used outside of the browser. It is primarily
|
|
focused on creating simple, easy to build network clients
|
|
and servers.
|
|
|
|
|
|
.SH OPTIONS
|
|
|
|
-v, --version print node's version
|
|
|
|
-e, --eval script evaluate script
|
|
|
|
-p, --print print result of --eval
|
|
|
|
-i, --interactive always enter the REPL even if stdin
|
|
does not appear to be a terminal
|
|
|
|
--no-deprecation silence deprecation warnings
|
