Two states of empty arrays

[Léa Gris]

Hello,

Depending on how an empty array is declared, it is not stored with the
same state.

# Empty array declared without parenthesis
unset myArr
declare -a myArr
typeset -p myArr
echo "${#myArr[@]}"

output:
declare -a myArr
0

# Empty array declared without parenthesis
unset myArr
declare -a myArr=()
typeset -p myArr
echo "${#myArr[@]}"

output:
declare -a myArr=()
0

What is the reason for having different states for empty arrays?
