// TypeScript is modular, we can divide our code up over several files
// In Angular 2 we then use  "import {} from ''" to access the code in these files

// We export a class, interface, variable, ... by adding 'export' keyword in front of it

export class ExportedClass {
    // This class is exported
}

// Generics are types which can hold/ use several types
// We're only touching the very basics here - you can go MUCH more into detail

// Consider the Array object

let numberArray: Array<number>; // This array will only accept numbers

// Try to initialize it with strings

// numberArray = ['test']; // => Error

// Interfaces allow us to create contracts other classes/ objects have to implement
// We can use them to define custom types without creating classes
// Interfaces ARE NOT compiled to JavaScript! It's just for checking/ validation done by our TypeScript compiler

// Example interface

interface User {
    username: string;
    password: string;
    confirmPassword?: string; // Optional property => Does not have to be implemented

// Classes allow us to create 'blueprints' for objects
// In Angular 2 we use classes a lot. For example to create Components, Services, Directives, Pipes, ...

// How to create a class

class Car {
    engineName: string;
    gears: number;
    private speed: number;
