[NTG-context] What's the difference between \dodoubleargument and \dodoubleempty?

You mean both of them ask the following \command to take two mandatory
arguments? I try this example:
==
\def\test
{\dodoubleargument\dotest} % use \dodoubleempty
\def\dotest[#1][#2]
{\iffirstargument
First arg: #1
\fi
\ifsecondargument
Second arg: #2
\fi}
\test[ok][ok] % 1. this is ok
\test [ok] [] % 2. warning?
\test [wrong] % 3. Error: lack one arg
==
both 1 and 2 can print First arg and Second arg, so I am confused what's
no argument is given

You need a comment sign at the end of the line.
\def\dotest[#1][#2]%
{\iffirstargument
First arg: #1
\fi
\ifsecondargument
Second arg: #2
\fi}
\test[ok][ok] % 1. this is ok
\test [ok] [] % 2. warning?
This is just a empty argument.
\test [wrong] % 3. Error: lack one arg
