Refactoring TypeScript
Refactoring TypeScript
Keeping Your Code Healthy
About the Book
You know that piece of code your teammates hate to touch? The one that keeps producing bugs?...
Much like a garden, our code will become overgrown with "weeds" if ignored. What if there was a way to identify these weeds? And, what if there was an approachable way to learn how we can fix these issues? That's what this book is about.
You'll learn some of the main causes of unhealthy code, tips to identify them and techniques to address them.
