This book aims to provide a casual introduction to the main features of the TypeScript language. This chapter covers:
The intended audience for this book (i.e. who did I imagine would be interested in reading it?)
Why learn TypeScript? What's the return on investment here?
Aren't there enough books out there already? Why write another one?
A more personal note on how I wrote the book for those of you interested in the mechanics and other metrics of such things.
