an outer value of 'this' is shadowed by this container code example

Example: an outer value of 'this' is shadowed by this container

In TypeScript (and ES6) exists two kinds of functions: The classic function declaration and the arrow function. Where the classic function declaration has the default floating binding logic for the this keyword - the arrow function will constantly use the value for this of the context containing the arrow function. In the example this will be the instance of the surrounding class.
