Refactoring TypeScript. Keeping your code healthy

Refactoring TypeScript. Keeping your code healthy

James Hickey

Ebook
Refactoring improves your code without changing its behavior. With refactoring, the best approach is to apply small targeted changes to a codebase. Instead of doing a huge sweeping change to your code, refactoring is better as a long-term and continuous enterprise. Refactoring TypeScript explains how to spot bugs and remove them from your code.

You’ll start by seeing how wordy conditionals, methods, and null checks make code unhealthy and unstable. Whether it is identifying messy nested conditionals or removing unnecessary methods, this book will show various techniques to avoid these pitfalls and write code that is easier to understand, maintain, and test.

By the end of the book, you’ll have learned some of the main causes of unhealthy code, tips to identify them and techniques to address them.
