\define is basically the same as \unexpanded\def. It uses a slightly
different syntax for specifying optional arguments:
\define[3]\foo{First: #1, Second: #2, Third: #3}
\unexpanded\def\foo#1#2#3{First: #1, Second: #2, Third: #3}
Furthermore, \define displays a message if the command is already
defined:
system > command '\foo' is already defined
However, ConTeXt happily overwrites the existing macro.

There is \defineexpandable, which uses the same syntax as \define,
but it's a simple \def, without \unexpanded which is the closest
replacement.
I don't think named parameters are possible with \define, but maybe
I'm mistaken.
\def\bar#first#second{First: #first, Second: #second}
For you information, there's also
\starttexdefinition mycmd #1
…
\stoptexdefinition
\starttexdefinition mycmd $#first #second
…
\stoptexdefinition
\starttexdefinition unexpanded mycmd #first #second
…
\stoptexdefinition
