Typescript Quickly

Summary TypeScript is JavaScript with an important upgrade! By adding a strong type system to JavaScript, TypeScript can help you eliminate entire categories of runtime errors. In TypeScript Quickly, you’ll learn to build rock-solid apps through practical examples and hands-on projects under the expert instruction of experienced web developers Yakov Fain and Anton Moiseev. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Strong typing can eliminate nearly all errors caused by unanticipated data values. With TypeScript, an enhanced version of JavaScript, you can specify types and type annotations so your code is easier to read and far less likely to fail at runtime. And because the core of TypeScript is standard JavaScript, it runs on all major browsers and can be used with frameworks like Angular, Vue, and React. About the book TypeScript Quickly teaches you to exploit the benefits of types in browser-based and standalone applications. In this practical guide, you’ll build a fascinating blockchain service app that takes you through a range of type-sensitive programming techniques. As you go, you’ll also pick up valuable techniques for object-oriented programming with classes, interfaces, and advanced features such as decorators and conditional types.

TypeScript Revealed is a quick 100-page guide to Anders Hejlsberg's new take on JavaScript. With this brief, fast-paced introduction to TypeScript, .NET, Web and Windows 8 application developers who are already familiar with JavaScript will easily get up to speed with TypeScript and decide whether or not to start incorporating it into their own development. TypeScript is ‘JavaScript for Application-scale development’; a superset of JavaScript that brings to it an additional object-oriented-like syntax familiar to .NET programmers that compiles down into simple, clean JavaScript that any browser can run today. It’s also tied to the next version of the JavaScript standard, which means that TypeScript will continue to evolve over time to keep in step with that standard and with the capabilities of the engines that will execute JavaScript applications. If you are a .NET developer, Web designer or developer, or a programmer with a keen interest in scalable applications, TypeScript Revealed is a great way to get started with the language, learn how it compiles into JavaScript, and how easy it is to learn from a .NET/Java developer's perspective. Takes you through the language features in Typescript additional to those in JavaScript Describes the tooling and community support for TypeScript development Discusses how TypeScript can be included in ASP.NET, Windows 8, and node.js application development projects. What you’ll learn Why you should care about TypeScript What it does and what it doesn't do The current toolset and levels of support The new syntax features of TypeScript How to build your own TypeScript declaration files How to incorporate TypeScript into your projects Who this book is for TypeScript Revealed is aimed at the early adopter developer who is already familiar with Microsoft tools and .NET and/or JavaScript development that wants a flavor of TypeScript distilled, culled, and organized in one place. Table of ContentsChapter 1: What is TypeScript? Why TypeScript? Chapter 2: New Syntax Static Typing & Type Inference Tooling Interfaces Classes Derived classes using the 'extends' keyword. Arrow functions Modules Enforcing the Intention of some features. Typescript vs EcmaScript6 Chapter 3: Working with TypeScript Tools & Resources

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

TypeScript is a typed superset of JavaScript with the potential to solve many of the headaches for which JavaScript is famous. But TypeScript has a learning curve of its own, and understanding how to use it effectively can take time. This book guides you through 62 specific ways to improve your use of TypeScript. Author Dan Vanderkam, a principal software engineer at Sidewalk Labs, shows you how to apply these ideas, following the format popularized by Effective C++ and Effective Java (both from Addison-Wesley). You’ll advance from a beginning or intermediate user familiar with the basics to an advanced user who knows how to use the language well. Effective TypeScript is divided into eight chapters: Getting to Know TypeScript TypeScript’s Type System Type Inference Type Design Working with any Types Declarations and @types Writing and Running Your Code Migrating to TypeScript
