How to create an array in bash?

In bash, arrays are created using the syntax:

# Declare an array
my_array=(element1 element2 element3)

# Or add elements one by one
my_array[0]=element1
my_array[1]=element2

# Access elements
echo "${my_array[0]}"  # will output element1

# Get all elements
echo "${my_array[@]}"

Arrays in bash are zero-indexed and can contain strings.
