An array is an ordered collection of objects that can be thought of as a list

length() is a method that returns the number of elements in the array.

You can check how many elements an array has with the length method.

					mixed = [5, "Hello World", "FRR", true, [1, 2, 3]]

print(mixed.length) # 5

Example 3

			
					array = ["Spring", "Summer", "Fall", "Winter"]
