Regular Expressions: A hands on introduction (Solving Acronym on Exercism)
In this video we take a gentle dive into regular expressions as we solve the Acronym exercise. We look at the most basic solutions (such splitting on whitespace) and end up with unicode and negative lookbehinds. We finish off by looking at some other approaches to Acronym including state machines!
Sit back and enjoy 45mins of learning with Jeremy and Erik, then go solve the exercise in your favourite way on Exercism.
