Essential TypeScript 2.1 with Visual Studio Code

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.

Prerequisite

Experience with JavaScript or an object-oriented programming language such as Java or C#

Expected Duration
5 day

Description

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 gives developer tools to provide IntelliSense and syntax checking so that errors are caught at compile-time instead of at run-time.

In this course, you will be provided with in-depth coverage of TypeScript, including language syntax as well as object-oriented and asynchronous programming. You will learn how to organize your code using namespaces and modules. You will also learn to use Visual Studio Code, Microsofts 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.
