Recursion has more expressive power than iterative looping constructs. I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive.

This Java recursion tutorial shows you how to create a recursive Java factorial function and compares these methods to iterative ones.

Algorithm design strategies such as divide and conquer. Elementary techniques for analysis; asymptotic analysis, recursion equations, estimation methods, elementary combinatorial arguments.

Some inventions operate in a recursive or iterative manner. This could be so of a machine that repeats actions or functions on a single article or to produce multiple articles, or operates on data.

For some data structures, some recursive algorithms are the most simple (read: maintainable) and elegant solutions.

Recursion releases open-source data from largest ever dataset of biological images and a machine learning competition available through NeurIPS 2019.
