ES6 Map and Set objects

[Californ1a]

When should each be used and what kind of data structures would require using them instead of typical objects or arrays.

• Map
• Set

As an aside, although this functionality isn't in the native ES6 Map, I particularly like the .find() functionality in this collection that extends the Map class where you're able to pass in a key/value pair and get the full object that contains that reference back. This sort of thing I find especially helpful for large nested objects (where a Map is most useful), and it is a fairly simple function to add to a class that extends Map since it's just one small loop to iterate through each item in the Map.

Anyway, I'd love to see a video on Maps, Sets, or other "Collection" types. Especially since these can also play really well into the higher-order functions that were looked at in a few videos recently.

Oh, I would love to do this! This is especially relevant for my fall class so someone should remind me then if I don't get to it beforehand.
