- 7. What is TypeScript? LifeMichael.com ● The TypeScript programming language was developed by Microsoft. It is an open source programming language. ● The code we write in TypeScript is transpiled into JavaScript, so we can basically use TypeScript wherever we use JavaScript. http://www.typescriptlang.org
- 8. What is TypeScript? LifeMichael.com ● TypeScript is a superset of JavaScript. It includes the entire JavaScript programming language together with additional capabilities. ● In general, nearly every code we can write in JavaScript can be included in code we write in TypeScript.
- 9. What is TypeScript? LifeMichael.com ● TypeScript's main added value is the ability to code with types. It allows us to define new classes and new interfaces. TypeScript allows us to specify the type of each and every variable and is even capable of interfering the type by itself. TypeScript allows us to use JavaScript as if it was a strictly type programming language.

- 11. What is Dart? LifeMichael.com ● Dart is an open source class based, object oriented, optionally typed programming language that allows us to develop browser based one page web applications. Dart can be used for the server side. ● Dart is developed by Google and the initial plan was to have a Dart VM installed on every web browser. http://www.dartlang.org
- 12. What is Dart? LifeMichael.com ● Using the Dart virtual machine we can execute the code written in Dart on the server side. ● We can execute the code either by using a web browser that supports Dart or by compiling the code into JavaScript.

LifeMichael.com class Rectangle { double _width; double _height; Rectangle(double w,double h) { width = w; height = h; } get width => _width; set width(size) => (size>0)?_width=size:_width=10.0; get height => _height; set height(size) => (size>0)?_height=size:_height=10.0; area() => width * height; perimeter() => 2*(width+height); }

- 15. What is CoffeeScript? LifeMichael.com ● CoffeeScript is a relatively small programming language we can use for writing code and later transpile it into JavaScript. ● CoffeeScript evolvement was inspired by Python and Ruby. CoffeeScript provides developers with tools similar to those you can find in Python and Ruby. http://www.coffeescript.org
