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?
