Programming TypeScript: Making Your JavaScript Applications Scale

Any programmer working with a dynamically typed language will tell you how hard it’s 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, writer Boris Cherny will teach you methods to master the TypeScript language. You’ll Be mindful how TypeScript mean you can do away with bugs to your code and provide help to scale your code across more engineers than it’s essential to 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: Be mindful TypeScript’s sophisticated type system, including methods to safely care for 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
