+Let’s consider a list of prices in a bill:

+We can write it as an array literal

+The Array object, as with arrays in other programming languages, enables storing a collection
+of multiple items under a single variable name, and has members for performing common array operations.
+Arrays can store items of any type & multiple pieces of information.

+In JavaScript, we can use [] notation to access specific elements in the array using index numbers.
+The index numbers start from 0.
