10 JUL 2026 - Back up to full speed! Let's be honest: for the last few months, TorrentFunk was painfully slow. Pages crawled, searches dragged, and just loading the site tested everyone's patience. We hunted the problem down to our network and rebuilt it from the ground up — smarter caching, a much bigger and faster connection, and a lot of fine-tuning under the hood. The difference is night and day: the site now loads in a fraction of a second. No more waiting around. Thanks for sticking with us through the slow spell. Now go discover your funk!

Regular Expressions For Beginners And Beyond! With Exercises
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 Concepts
In this course, we will cover concepts from basic to advanced:
Quantifiers
Character collections, including negation
Character ranges
String boundaries
Character Classes
Flags
Greedy vs. Lazy Quantifiers
Multi-Character Quantifiers and Options
Capturing Groups (numbered and named)
Substitution / Replace
Lookahead and Lookbehind
Depending 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 Examples
Examples 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 Exercises
There 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 supposed to. These exercises are a great way to cement the concepts in your brain, and make sure you really understand the material presented in the lectures.
Course Tools
The course uses regex101 (with permission of the author) to show how regular expressions match the test strings. There are also slides breaking down each regular expression example and explaining each piece.
Questions encouraged!
Please use the Q&A feature on Udemy to ask questions! I love to talk about why regular expressions don’t seem to be working, discussing decisions I made about course content, and debating regular expression philosophy.
Who this course is for:
Curious folks new to regular expressions
Developers looking to sharpen or expand their regular expression skills
Requirements
None! We will be using the regex101 web site to test our regular expressions, so all you need is a computer and web access
