Array objects with whitespace in names not conjoined

Question

AVAILABLEDIR=("${AVAILABLEDIR[@]}" "$(ls $LOC -AFl | sed "1 d" |  grep "/$" | awk '{ print $9,$10 }')")

I'm trying to create an array using this command, however when it adds objects to the array, it adds $9 and $10 seperately, is there a way to tell the array to have both of these arguments joined? This is what I want:

[Directory 1/] [Directory 2/] [Directory 3/]

instead of

[Directory] [1/] [Directory] [2/] [Directory] [3/]

Thank you for your help

It looks like you ask about that homework twice a day, and at least one of my answers shows how to scan a directory even if the entry names contains spaces. — Hans Klünder

Don't use a pipeline headed by ls for this; just use a glob.

pushd "$LOC"
AVAILABLEDIR+=( */ )
popd

pushd works like cd, but saves the current directory on a stack before changing. */ is a pattern that matches all directory names in the current directory; += appends the matching directories to the current value of AVAILABLEDIR. popd removes the directory name from the top of the stack and cds there. The pushd/popd combination is the easiest way to add Directory 1, rather than $LOC/Directory 1, to the array.

I don't really understand this code, is there a simpler way?

I literally do not know how this could be any simpler (using length as the measurement of complexity) but I will add an explanation for what each part does, which is worth understanding.
