  ### Use multiple classes together
  -Because [TimeStamps](#timestamps) dosnt extend [Base](#base), you can combine them like below, but because multiple extends are not supported nativly in ES/JS/TS, you have to use mixins
  --> [Look at Typescript guide to understand this](https://www.typescriptlang.org/docs/handbook/mixins.html)
  +Because Typescript & JavaScript dont have functions for multiple inheritance, it can only be achived by the following
  ```ts
  -interface Something extends Base, TimeStamps {} // have the interface to override the types
  -class Something {} // have your class
  -applyMixins(Something, [Base, TimeStamps]); // apply the two other classes
  +interface Something extends Base {} // have the interface to add the types of "Base" to the class
  +class Something extends TimeStamps {} // have your class
  ```
  +
  +Note: This only works because `Base` only has types and does not modify anything
