[Discussion] Ideas for new Concepts

[junedev]

Concept Roadmap

There are already a lot of ideas for additional concepts that we could cover with concept exercises in the future.
You can find a list in our roadmap document: Roadmap - Potential Future Concepts

We already created issues for the following new concepts/exercises:

• Implement new Concept Exercise: Template Strings and Ternary #1009
• Implement new Concept Exercise: Classes #1015 (claimed)
• Implement new Concept Exercise: Async/Await #1502 (claimed)
• Implement new Concept Exercise: Regular Expressions #1506
• Implement new Concept Exercise: Randomness #1515 (claimed)
• Implement new Concept Exercise: Dates #1528 (claimed)
• Separate rest-and-spread into its own new concept exercise (concept exists) #1500
• Elyses Destructered Enchantments: Add object destructering and remove rest and spread #1501

Additionally some concept exercises that exist but need major improvements are not yet visible on the website (status "wip"), see #1415.

Purpose of this issue

• Suggest additional concepts to cover that are not on the roadmap yet.
• Comment on which concept from the roadmap you would like to see implemented first.
• Volunteer for creating a certain concept exercise that does not have an issue yet, so a maintainer can write up an issue with some basic guidelines for you.
• General discussion about how to divide concepts/ how to structure the concept tree.
• etc

Additional ideas by @Steffan153 (posted here #951 (comment), items already on the roadmap are omitted below):

• WeakMap/WeakSet
• WeakRef and FinalizationRegistry
• Proxy and Reflect (reflect is not on the list yet)
• Decorators

I'd like to suggest adding a functional composition concept. The exercise coordinate-transformation mentions them but the exercise only covers the concept of closures.
