Documentation: Add JSDoc to types.ts #103

What should be changed?

• An example is missing
• Existing documentation needs to be extended
• Something else, state below: JSDoc documentation is missing.

Description

For better usage of our props we can document them a bit more. This issue is quite easy and just involves documentation but also some understanding of how our components work.

A pull request for this issue should just add JSDoc comments for the src\types.ts file.

To explain from my own words what the things are used for:

• IInOption: an option that will be shown on the left side of the selector in the component
• IInOption.name: The name/label to show the option for. Could be "English", "German" or similar in the case of Google Translate
• IInOption.active: Shows if the current option is active
• IInOption.key: the key, mostly used because of: https://reactjs.org/docs/lists-and-keys.html
• InOptions: An array of IInOption
• IOutOption: The same as IInOption. An option that will be shown on the left side of the selector in the component. You can mention that another parameter was added to the interface.
• IOutOption.activeClicked: Is a bit different than active because it shows a different color.
• OutOptions: An array of IOutOption

Please rephrase these sentences so they makes sense. Resources that helped me to understand JSDoc comments:
