You become very good at identifying ways in which to avoid writing error-prone loops. You also get a sense for how to use simple functions of various types rather than more abstract and purpose-built abstractions. A neat example of the later: dependency injection is a massively more complicated concept than just passing functions that provide a value, while providing even greater flexibility and more obvious reuse.
