Map, Set, WeakMap

This meetup will be very hands on, no slides, no talks - just talking, thinking, coding and sharing. Very often we do mob-programming, sometimes even in two mobs.

This time we will discuss only the `Map`, `Set` and `WeakMap`, which exists in JavaScript since ES6. On MDN https://developer.mozilla.org/en-US/search?q=map+weakmap+set there are many results when searching. There is enough room for learning :).

After talking and generating common understanding, we are going to work on one dedicated task that can be solved with it. If you have any interesting real-life use case for it, please come forward and we let the participants decide which problem we will try to solve. Very often we did mob-programming. Depending on the size of the group we might also split into smaller groups or do pair-programming. We are flexible :).
