The bash shell has simple variables and one-dimensional array variables. That one is simply creating an empty array.

You can see the effect in the following transcript which creates arrays of varying sizes and shows you their size:

pax> x=(1 2 3 4 5) ; echo ${#x[@]}
5
pax> x=(1) ; echo ${#x[@]}
1
pax> x=() ; echo ${#x[@]}
0

Try reading the documentation. See https://www.gnu.org/software/bash/manual/bashref.html#Shell-Parameters

VarName=1
VarName="two"
