You have to know THIS (in TypeScript)

The binding of "this" is dependant of the callee and the environment of your TypeScript code. In a browser environment, the global object refers to "window" which can be referenced by "this". In Node.js, the global object is called "global" and can also be referenced by "this". In his video, Benny will explain you how "this" behaves and how you can change its default behaviour.
