What is array?
An Array is an object type designed for storing data collections.
Key characteristics of JavaScript arrays are:
Elements: An array is a list of values, known as elements.
Ordered: Array elements are ordered based on their index.
Zero indexed: The first element is at index 0, the second at index 1, and so on.
Dynamic size: Arrays can grow or shrink as elements are added or removed.
Heterogeneous: Arrays can store elements of different data types (numbers, strings, objects and other arrays).
const cars = ["Saab", "Volvo", "BMW"];
Output: Saab, Volvo,BMW
