9.  JavaScript augmented by
 class-based OOP of ES6
 structural type system of ES4.
 Our code is being compiled to regular JavaScript and
supposed to work on any browser
 Easy integration with existing JavaScript code
 Provides optional static typing, classes, interfaces, generics
and modularity
 Generated code follows the “good parts”
 Ready for large enterprise applications

11.  Visual Studio, Visual Studio Code and WebMatrix
 IntelliJ IDEA, WebStorm and PhpStorm
 Eclipse and NetBeans
 Sublime Text
 Emacs and Vim
 Atom
 Brackets
 Plugins for Grunt, Gulp, Maven
 TSLint
 and more...

12. Install NodeJS
https://github.com/nodejs/node
Install Typescript compiler
npm install –g typescript
Compile a file
tsc example.ts

13.  Datatypes
 Functions
 Classes and Interfaces
 Generics
 Modules

14.  Boolean
 Number
 String
 Array
 Enum
 Any
 Void

20.  >250 languages compiles to JavaScript
 Keep using JavaScript. Try Babel to start using the next generation
JavaScript right now.
 If you want static type checking, better tools, want a short learning curve
from JavaScript or already know C#/C++/Java then try TypeScript
 If you want more concise code, lots of syntactic sugar or already know Ruby
then try CoffeeScript

21. “Microsoft’s TypeScript may be the best of the many JavaScript
front ends. It seems to generate the most attractive code.”
Douglas Crockford
“What impressed me most is TypeScript doesn’t do. It doesn't
output type checking into your JavaScript code.”
Nicholas C. Zakas
"CoffeeScript is to Ruby as TypeScript is to Java/C#/C++."
Luke Hoban (co-creator of TypeScript)
