Use arrays, has no array use example

[EvanTheB]

Hello,

The section on using arrays could really do with an example of using an array in a loop.

https://github.com/anordal/shellharden/blob/master/how_to_do_things_safely_in_bash.md#use-arrays-ftw

maybe

xs=(
 a
 b
)
for x in "${xs[@]}" ; do 
 echo "$x"
end

But I did not submit a PR because I am not sure that is actually correct.

Thanks for the great resource!

Thanks for the tip!

LGTM, except that "end" should be "done". Are you using fish? So am I. ;-)

I'll look at this later today, and see how it fits in.

I expanded the array example with a loop: 55fc9ed
