Recursion is (in many, but not all) languages slightly slower, and it does have some dangers (smashing the stack), but used properly it's a completely legitimate, valuable tool for production code.

Java factorial recursion explained Notice how the recursive Java factorial function does not need an iterative loop. Instead, the code repeatedly calls itself until a stop condition is met. In this ...

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 ...

Arguably the recursive code itself wasn't the problem, but it did complicate the debugging. Just to provide some examples for those that are asking, here's some anti-patterns I've seen of the years: ...
