Calling the::new method with zero, one, or more than one arguments creates a Ruby array. arrayName = Array. new is the syntax.

The simplest approach to print the contents of an array is to pass the array as a parameter to the puts or print method. On a separate line, each element is printed. The output is more readable when the examine method is used. The line outputs the array's string representation to the terminal.

Ruby arrays are collections of any object that are sorted and integer-indexed. An index is assigned to each element in an array and is used to refer to it.
