2. If there is a bucket that stores something in
it, to name the bucket with the item that is
stored in it, is what you will call a data type.
int, double, String, bool, List, Map...
Why do we have data types? Whenever a
variable is created to store data, we can
specify the type of the data.

We can use some power that is given by each data
type to manipulate or to look at the data.
Such as:
String name = "Pratik";
name.length;
name.toLowerCase();
