So the following commands are giving me different answers than I expect.

Code:

#!/bin/sh

array_2=('1 2' 3 4)

echo With '"$@":'

for i in "${array_2[@]}"
do
    echo $i
done


echo With '$@:'

for i in ${array_2[@]}
do
    echo $i
done

Output:

With "$@":
1 2
3
4


With $@:
1
2
3
4

Why is $@ "not seeing" that '1 2' are enclosed by single quotes, when "$@" can?
