The Fibonacci sequence is a series of numbers where the next number is calculates adding the two previous numbers. This sequence begins with two numbers: zero and one. The third number is calculated adding these two numbers (0 + 1). The fourth number is calculated adding the two numbers before it (1 + 1). And so on.
Having a position, the function returns the value that corresponds to that position in the Fibonacci sequence.
