title: Why use recursion?
body: <p>I am wondering, why do people use recursion? In most of my learning experience, I've found it to be much more inefficient that iterative methods, so why do people use it? Is it because you can simply write a shorter method? Is it used in real-world programming outside the classroom setting (or learning purposes)? If it is, please provide a good example if you can, I'm very curious.</p>
  
  <p>Thanks in advance for your help! I really appreciate it!</p>
