Keeping it Regularby in CodeSOD on 2016-10-24
Regular expressions are like one of those multi-tools: they're a knife, they're a screwdriver, they're pliers, and there's a pair of tweezers stuck in the handle. We can use them to do anything.
For example, Linda inherited a site that counted up and down votes, like Reddit, implemented in CoffeeScript. Instead of using variables or extracting the text from the DOM, this code brought regular expressions to bear.
