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. 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 * Book description: © Manning: https://www.manning.com/books/five-lines-of-code The interview is based on the book "Five Lines of Code": https://amzn.to/3s2zjyg TIMECODES 00:00 Intro 01:17 From teenage programmer to agile guru 04:14 Unleashing the power of small 07:50 The power of effective programming 10:08 The pitfalls of automation 13:05 Strategic copying: Maximizing codebase agility 16:56 The art of doing one thing at a time 22:17 Is automating refactoring a mistake? 32:38 Communication is hard, do it more often 35:07 Overcoming barriers in software development 39:08 TypeScript, getters & setters, code quality & code visibility 48:44 Building better code with invariants 56:32 Into the danger 01:01:48 Fear-proof your code & overcome challenges to deliver great software 01:07:27 Outro RECOMMENDED BOOKS Christian Clausen • Five Lines of Code • https://amzn.to/3s2zjyg Kevlin Henney & Trisha Gee • 97 Things Every Java Programmer Should Know • https://amzn.to/3kiTwJJ Kevlin Henney • 97 Things Every Programmer Should Know • https://amzn.to/2Yahf9U Martin Fowler • Refactoring 2nd Ed. • https://amzn.to/3EVcHXQ Fowler, Beck, Brant, Opdyke, Roberts & Gamma • Refactoring 1st Ed. • https://amzn.to/43Qgob8 Edsger W.
