Description: Regular expressions have a bad reputation for being difficult to understand. This course introduces tools and a systematic approach so you can unlock the power of regular expressions to write compact, elegant code.  Course ConceptsIn this course, we will cover concepts from basic to advanced:QuantifiersCharacter collections, including negationCharacter rangesString boundariesCharacter ClassesFlagsGreedy vs. Lazy QuantifiersMulti-Character Quantifiers and OptionsCapturing Groups (numbered and named)Substitution / ReplaceLookahead and LookbehindDepending on your level of experience, you can start at the beginning, or start later with concepts you've always been interested in, but haven't had a chance to learn yet. Course ExamplesExamples progress in a logical, narrative way. At the end of one example, we will think about how we might tweak it to do something similar but more powerful. In this way, the concepts flow naturally from one example to the next.The course has 44 examples in the course of the lectures, each written out on different platforms (JavaScript / Python / Linux (grep)) in the course repository. Each regular expression is fully commented and has test cases to show how it's intended to be used, so these are a great starting point if you like to "code by example" -- start with an example you know works and tweak it for your purposes. Course ExercisesThere are also 46 exercises using Udemy's code challenge platform. You are given a description of a regular expression, and then you write it using your choice of JavaScript or Python syntax. After you're done, tests written especially for the exercises will let you know whether your regular expressions did the job they were supp
