About the Book

The audience of this book are software developers with experience of front end development who want to learn how to overcome the challenges of working on large JavaScript projects. If you’ve learned the fundamentals of JavaScript and perhaps built some Angular or React applications, and are now looking to get heavily involved in something bigger – one of those “career defining” challenges – then this book is for you. I will distill what I’ve learned as a front end developer in senior and lead positions into generally applicable knowledge that will help you to build large, stable and performant front end applications.
