Overview

TypeScript is a superset of JavaScript that compiles to plain JavaScript that can run in any browser and on any platform.  It supports the latest JavaScript features, including those from ECMAScript 2015, as well as proposed features from future JavaScript versions, such as decorators and async / await.  But what makes TypeScript ideal for large web applications is the addition of optional type annotations, which allow developer tools to provide intellisense and syntax checking, so that errors are caught at compile-time instead of at run-time. This course provides in-depth coverage of TypeScript, including language syntax, object-oriented and asynchronous programming, and how to organize your code using namespaces and modules.  You will also learn to use Visual Studio Code, Microsoft’s lightweight cross-platform code editor, to build RESTful services in TypeScript with Node.js, as well as responsive client applications with Angular 2, which is itself written in TypeScript.

Note: You may use your own laptop with Windows, OS X or Linux.

Target Audience

Developers who want to build client or server JavaScript applications using TypeScript with Visual Studio Code for improved productivity with intellisense, debugging and code refactoring.
