About this course

Working with text data is one of the most common tasks in programming, yet handling whitespace, punctuation, and formatting can lead to unexpected bugs. This course teaches you how to process strings and count words reliably in Ruby, ensuring your applications handle user input and text files with precision. You will start with the core concepts of string storage and progress to writing clean, maintainable parsing logic. By the end of this course, you will be able to confidently manipulate text, implement robust word-counting logic, and apply modern Ruby conventions to your codebase. What you'll learn: - Understand how Ruby stores and processes string data at a foundational level - Apply the split method with regular expressions to handle complex spacing and line breaks - Clean and normalize raw text by stripping whitespace and removing unwanted punctuation - Implement type hints and write clean, idiomatic Ruby code using modern helper methods - Write basic unit tests to verify your string manipulation logic handles edge cases We begin with essential terminology and the mechanics of string objects in Ruby. Next, you will explore the nuances of the split method, progressing from basic space tokenization to advanced pattern matching. Finally, you will learn to structure your code into reusable methods and verify your results with simple testing patterns. This course is designed for beginners who are new to Ruby or looking to strengthen their text processing skills. No prior programming experience is required.
