Say goodbye to the intimidating reputation of regex and embrace their true potential! 🛠️➡️✨

Course Overview

Dive into a journey through the fundamentals and nuances of regular expressions with this engaging course. We'll explore a wide array of concepts, from simple patterns to complex constructs, ensuring that you can apply regex principles in various programming contexts. With a focus on clarity and practical application, you'll be able to manipulate strings with confidence.

Course Concepts 📚

We'll cover an extensive range of regex concepts, each explained in clear, accessible terms:

• Quantifiers: Understand how to specify the number of character occurrences precisely.
• Character Collections: Master using sets and negation to define a wide array of possible characters.
• Character Ranges: Learn how to define a sequence of characters within a specific range.
• String Boundaries: Discover how to target exact strings in larger text blocks.
• Character Classes: Explore patterns that can match multiple characters at once.
• Flags: Understand the various flags that alter regex behavior and output.
• Greedy vs. Lazy Quantifiers: Learn when to use each type of quantifier for optimal matching.
• Multi-Character Quantifiers and Options: Get to grips with patterns that can handle more complex character requirements.
• Capturing Groups (numbered and named): Find out how to extract specific parts of matched strings.
• Substitution / Replace: Master the art of replacing parts of a string according to your needs.
• Lookahead and Lookbehind: Learn how to preview or peek at future/past text without consuming it in your regex.

Course Examples 🎬

Our course features a series of logical, narrative examples. Each example is written in JavaScript, Python, or for Linux (grep) users, and includes comprehensive comments for clarity. These real-world applications are designed to build your understanding incrementally. Plus, each example comes with test cases to illustrate how it should be used, providing a solid foundation for coding by example.

Course Exercises 🏋️‍♂️

To reinforce your learning and ensure you truly grasp the concepts, this course includes 46 exercises. You'll be presented with a scenario and asked to write a regular expression in either JavaScript or Python. Afterward, you can test your regex against a set of designed scenarios to see how well it performs. These exercises are not just optional—they're essential for mastering the material covered in the lectures.

Course Tools 🛠️

To aid your learning, we utilize regex101 (with permission from the author) to demonstrate how regular expressions interact with test strings. Additionally, there are detailed slides that break down each example and explain the components involved, ensuring you have a thorough understanding of the regex at play.

Engage and Learn 💬
