If your jаvascript is a mess, frameworks can only do so much to help. No matter what framework, "compiles-to-JS" language, or library you use, bugs and performance concerns will always be an issue if the underlying quality of your jаvascript is poor. With this hands-on guide, you’ll learn how test and refactor your existing code to help reduce complexity, improve readability, and gain confidence in the codebase.

Author Evan Burchard shows you how to identify areas of bad code, and then takes you through several refactoring methods for improving them. Techniques range from renaming variables to applying principles of functional and object-oriented programming. If you’re motivated to write better jаvascript code either on the frontend or backend, this book is a must.
