Exploit the features of TypeScript to develop and maintain captivating web applications with ease

About This BookLearn how to develop modular, scalable, maintainable, and adaptable web applications by taking advantage of TypeScriptCreate object-oriented JavaScript that adheres to the solid principles efficientlyA comprehensive guide that explains the fundamentals of TypeScript with the help of practical examplesWho This Book Is ForIf you are a JavaScript developer aiming to learn TypeScript to build beautiful web applications, then this book is for you. No prior knowledge of TypeScript is required.

What You Will LearnLearn the key TypeScript language features and language runtimeDevelop modular, scalable, maintainable, and adaptable web applicationsCreate object-oriented code that adheres to the solid principlesSave time using automation tools like Gulp and KarmaDevelop robust applications with testing (Mocha, Chai and SinonJS)Put your TypeScript skills in practice by developing a single-page web application framework from scratchUse the JavaScript of tomorrow (ES6 and ES7) today with TypeScriptIn DetailTypeScript is an open source and cross-platform typed superset of JavaScript that compiles to plain JavaScript that runs in any browser or any host. It allows developers to use the future versions of JavaScript (ECMAScript 6 and 7) today. TypeScript adds optional static types, classes, and modules to JavaScript, to enable great tooling and better structuring of large JavaScript applications.

This book is a step-by-step guide that will get you started with TypeScript with the help of practical examples. You start off by understanding the basics of TypeScript. Next, automation tools like Grunt are explained followed by a detailed description of function, generics, callbacks and promises. After this, object-oriented features and the memory management functionality of TypeScript are explained. At the end of this book, you will have learned enough to implement all the concepts and build a single page application from scratch.

Style and approachThis is a step-by-step guide that covers the fundamentals of TypeScript with practical examples. Each chapter introduces a set of TypeScript language features and leads the readers toward the development of a real-world application.

Solid book, but it's probably not what you would expect. A lot of it was not directly related to TypeScript, like SOLID principles, OOP, developing author's own MVC frontend framework. Not sure how exactly TS looked like in 2015, but surely it has come a long way since then. Is the book worth reading today (2022) is kind of moot depending on what you are looking for. Most likely not. Paradoxically, the strongest parts are unrelated to TS. If you want to learn it, look for other resources. To be honest, I read the book only because I got it for free from Packt.

I don't think I'd recommend this as a book that someone should read to learn TypeScript/Javascript. However, it does bring up some interesting concepts (like category theory, the different Web UI frameworks available in TypeScript/Javascript, and the TypeScript compiler libraries).

A good book. However, this book is much more about design patterns using typescript rather than "Learning Typescript". I believe the title doesn't represent exactly what this book has to offer. Give an overlook before start reading. If you are looking for a kind of deep typescript reference book, this book may not suit your expectations.

This was a reasonably good introduction to TypeScript. The book goes beyond TypeScript to cover some stuff about modern JavaScript development in general, including developing a full MVC app in TypeScript. This was somewhat interesting to me, since I wasn't really aware of some of that stuff.

(This was a free ebook from Packt.)
