TypeScript Programming Language
TypeScript for Programmers TypeScript lets you write JavaScript the way you really want to. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. TypeScript is pure object oriented with classes, interfaces and statically typed like C# or Java. The popular JavaScript framework Angular is written in TypeScript. Mastering TypeScript can help programmers to write object-oriented programs and have them compiled to JavaScript, both on server side and client side. This is a book for programmers of all walks: professional JavaScript engineers, C# people, Java sympathizers, Python lovers, Ruby aficionados, Haskell nerds. Whatever language(s) you write in, so long as you have some experience programming and know the basics of functions, variables, classes, and errors, this book is for you. Some experience with JavaScript, including a basic knowledge of the Document Object Model (DOM) and the network, will help you along the way while we don't dive deep into these concepts, they are a wellspring of excellent examples, and if you're not familiar with them the examples might not make as much sense. Regardless of what programming languages you've used in the past, what unites all of us is our shared experience of tracking down exceptions, tracing through code line by line to figure out what went wrong and how we can fix it. This is the experience that TypeScript helps prevent by examining your code automatically and pointing out the mistakes you may have missed. It's OK if you haven't worked with a statically typed language before. I'll teach you about types and how to use them effectively to make your programs crash less, document your code better, and scale your applications across more users, engineers, and servers. I'll try to avoid big words when I can, and explain ideas in a way that's intuitive, memorable, and practical, using lots of examples along the way to help keep things concrete. That's the thing about TypeScript: unlike a lot of other typed languages, TypeScript is intensely practical. It invents completely new concepts so you can speak more concisely and precisely, letting you write applications in a way that's fun, modern, and safe. What you will learn in this book: - introduction to Typescript - Environment setup - Program structure - Basic syntax - Data types - Variables - operators - Decision making - Loops - Arrays - Much, much, more!
Typescript Mini Reference
Become a Better Javascript Programmer! Typescript is a better Javascript, It is a statically typed, safe programming language, which uses more or less the same syntax as Javascript. Typescript programs are compiled to Javascript, and they can be run anywhere Javascript is supported. It is widely used by professional Javascript developers, for frontend development (e.g., Angular, React, and VueJS) as well as for backend development (e.g., Node.Js and Deno). This book is a "mini" language reference on the Typescript programming language. We go through all essential features of Typescript (as of versions 4.8 and 4.9), and some new ECMAScript features, in this book. Although it is written as a reference, however, you can read it more or less from beginning to end and you should be able to get the overall picture of the Typescript language if you have some prior experience with programming in Typescript or modern Javascript (ES2015 and later). This book is, however, not intended for complete beginners. The book covers * Typescript development basics. * ES module system. * Basic JS/TS types. Type annotations. * Variable declarations. Type inference. * Algebraic data types. Generics. * Objects. Classes. * Function types. Arrow functions. * How to create new types from existing types. Order your copy today!
Programming with Types
Summary Programming with Types teaches you to design safe, resilient, correct software that’s easy to maintain and understand by taking advantage of the power of strong type systems. Designed to provide practical, instantly useful techniques for working developers, this clearly written tutorial introduces you to using type systems to support everyday programming tasks. About the technology Common bugs often result from mismatched data types. By precisely naming and controlling which data are allowable in a calculation, a strong type system can eliminate whole classes of errors and ensure data integrity throughout an application. As a developer, skillfully using types in your everyday practice leads to better code and saves time tracking down tricky data-related errors. About the book Programming with Types teaches type-based techniques for writing software that’s safe, correct, easy to maintain, and practically self-documenting. Designed for working developers, this clearly written tutorial sticks with the practical benefits of type systems for everyday programming tasks. Following real-world examples coded in TypeScript, you’ll build your skills from primitive types up to more-advanced concepts like functors and monads. What's inside Building data structures with primitive types, arrays, and references How types affect functions, inheritance, and composition Object-oriented programming with types Applying generics and higher-kinded types About the reader You’ll need experience with a mainstream programming language like TypeScript, Java, JavaScript, C#, or C++. About the author Vlad Riscutia is a principal software engineer at Microsoft. He has headed up several major software projects and mentors up-and-coming software engineers.
