This document discusses TypeScript and provides information about its features and how to install and use it. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript and can be used for application-scale development. It provides features like types, classes, inheritance and interfaces to support building large applications. The document also provides instructions for installing TypeScript, Node.js, NPM and configuring IDEs to use TypeScript.

8. ClearJS
function Greeter(greeting) {
this.greeting = greeting;
}
Greeter.prototype.greet = function () {
return "Hello, " + this.greeting;
};
var greeter = new Greeter("world");

9. Types
function Greeter(greeting: string) {
this.greeting = greeting;
}
var greeter = new Greeter("world");

10. Types
function Greeter(greeting: string) {
this.greeting = greeting;
}
var greeter = new Greeter("world"); // ok
var bad = new Greeter(5); // bad

12. Classes
class Greeter {
greeting: string;
constructor(message: string) {
this.greeting = message;
}
greet() {
return "Hello, " + this.greeting;
}
}
var greeter = new Greeter("world");

13. Inheritance
class Animal {
constructor(public name: string) { }
move(meters: number) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name: string) { super(name); }
move() {
alert("Slithering...");
super.move(5);
}
}
var sam = new Snake("Sammy the Python");
sam.move();

14. Modules
module Sayings {
export class Greeter {
greeting: string;
constructor(message: string) {
this.greeting = message;
}
greet() {
return "Hello, " + this.greeting;
}
}
}
var greeter = new Sayings.Greeter("world");
