What is a "a general permutation algorithm"?

Do you mean you want a function that does something,
having externally defined arrays as input-parameters?

> extend the code

Here is the problem.

"You" do not "extend" a convoluted code to make it more general,
as its convolution will grow [perhaps even exponentially].

"You" start over again, explaining to yourself what such code must/should 
do, and then build an experimental function in a test-file full of 
breakpoints and/or console.log lines.
