| Summary |
Starting with an introduction to the language and its features, the book discusses some of the major features of TypeScript in depth, from working with the type system through object-orientation to understanding the runtime and the TypeScript compiler. The book then covers some of the factors to be considered when running a TypeScript application in the browser, including interacting with the DOM, making asynchronous requests, and working with useful browser APIs, followed by a demonstration of server-side TypeScript using the popular Node.js framework. Topics covered include: key TypeScript language features; how to work with the TypeScript type system; how to transfer object-orientation skills to TypeScript; useful JavaScript patterns and features that work well with TypeScript; how to consume existing JavaScript libraries in TypeScript program; how to run TypeScript in a web browser or on a server. -- Edited summary from book. |
