What is array?

An array is a data structure that stores a collection of items, each identified by one or more indices. It is used to store a set of related items, usually in the same data type, and access them efficiently. Arrays are most commonly used in computer programming languages to store multiple values in a single variable. This is especially useful when working with large sets of data, as it allows for efficient data manipulation. Arrays can be seen as a form of a list, as they are usually composed of multiple elements that are organized in a certain order.

# The .map! method is being used to iterate through the array, and for each item, increase its value by 1. The ! at the end of the method call is used to signify that the values of the array will be mutated in place, rather than a new array being returned. Finally, the method returns the array with the updated values.
