  1. The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

  2. You use ordinal numbers to access and to set values inside an array; you also start from 0 instead of 1.
