Welcome

- [Narrator] TypeScript has been taking the web world by storm, and with good reasons. It provides a Typesafe object-oriented language that transpiles to JavaScript. To learn TypeScript however, you need not know any JavaScript, and we'll be looking at TypeScript as a first class language particularly suited to C# programmers because it uses many of the same constructs, extractions, and even syntax of C#. Hi, I'm Jesse Liberty, and I've been writing production C# code as well as books and videos about C# for the past 16 years.

It is a tremendously flexible and powerful language, and its creator, Anders Hejlsberg, is also responsible for the development of TypeScript. I've been loving TypeScript because it is, essentially, a web programming language for C# developers. In this course we'll cover TypeScript types, Flow Control and functions. We'll look at default and optional parameters, rest parameters, and function overloading. We'll also explore lambda functions, object literals, and the creation and use of classes.

As we discuss object oriented programming, we'll take a look at derived classes and interfaces. In short, this is a comprehensive introduction to TypeScript programming aimed directly at experienced C# developers. So with that overview, let's dive right in.
