6,421 PointsWhy do I need to do `puts grocery_list.inspect` ? Why can't I just do `puts grocery_list`?
I tried both, and they both seem to do the same...show me the array of grocery_list.

.inspect() Is basically the same thing as .to_s. They convert arrays into strings.
If you call puts on an array itself, for example:
my_list = [1, 2, 3]
puts my_list
It will print:
1
2
3
However, if you first inspect the array, it will look like:
my_list = [1, 2, 3]
puts my_list.inspect
It will print:
[1, 2, 3]
As you see, with inspect, it will print the array raw. Without it will print it in the pretty format.
