Any programmer working with a dynamically typed language will tell you how hard it is to scale
to more lines of code and more engineers. That's why Facebook Google and Microsoft invented
gradual static type layers for their dynamically typed JavaScript and Python code. This
practical book shows you how one such type layer TypeScript is unique among them: it makes
programming fun with its powerful static type system. If you're a programmer with intermediate
JavaScript experience author Boris Cherny will teach you how to master the TypeScript
language. You'll understand how TypeScript can help you eliminate bugs in your code and enable
you to scale your code across more engineers than you could before. In this book you'll: Start
with the basics: Learn about TypeScript's different types and type operators including what
they're for and how they're used. Explore advanced topics: Understand TypeScript's
sophisticated type system including how to safely handle errors and build asynchronous
programs. Dive in hands-on: Use TypeScript with your favorite frontend and backend frameworks
migrate your existing JavaScript project to TypeScript and run your TypeScript application in
production.
