Description
In Video Editions the narrator reads the book while the content, figures, code listings, diagrams, and text appear on the screen. Like an audiobook that you can also watch as a video.

Down to earth, focused, and right on point. It will challenge you without intimidating you and without insulting your intelligence.
Robert C. Martin

In Five Lines of Code you will learn:

   The signs of bad code
   Improving code safely, even when you don’t understand it
   Balancing optimization and code generality
   Proper compiler practices
   The Extract method, Introducing Strategy pattern, and many other refactoring patterns
   Writing stable code that enables change-by-addition
   Writing code that needs no comments
   Real-world practices for great refactoring

Improving existing code—refactoring—is one of the most common tasks you’ll face as a programmer. Five Lines of Code teaches you clear and actionable refactoring rules that you can apply without relying on intuitive judgements such as “code smells.” Following the author’s expert perspective—that refactoring and code smells can be learned by following a concrete set of principles—you’ll learn when to refactor your code, what patterns to apply to what problem, and the code characteristics that indicate it’s time for a rework.
about the technology

Every codebase includes mistakes and inefficiencies that you need to find and fix. Refactor the right way, and your code becomes elegant, easy to read, and easy to maintain. In this book, you’ll learn a unique approach to refactoring that implements any method in five lines or fewer. You’ll also discover a secret most senior devs know: sometimes it’s quicker to hammer out code and fix it later!
about the book

Five Lines of Code is a fresh look at refactoring for developers of all skill levels. In it, you’ll master author Christian Clausen’s innovative approach, learning concrete rules to get any method down to five lines—or less! You’ll learn when to refactor, specific refactoring patterns that apply to most common problems, and characteristics of code that should be deleted altogether.
about the audience

For developers of all skill levels. Examples use easy-to-read Typescript, in the same style as Java and C#.
