Task 0

Prepare GitHub repo for Tasks

Task 1

Choose array fn (map/filter/filterMap/some/find/findIndex)
Prepare its callback based async counterpart
Prepare demo cases for the usage
Add new on-demend feature during review e.g.: Add support for debounce (if the task took less then X time to complete -- add an additional execution delya)

Task 2

Prepare promise based alternative
Write use cases for the promise based solution
Write use cases for the async-await
Add new on-demend feature during review e.g.: Add support for parallelism
Note: for technologies that do not have the native Future-like async functionalities You may combine Task 1 and 2 into a single Task that will showcase the idiomatic way of handling concurrency.

Task 3

Integrate AbortController or other Cancallable approach

Task 4

(Stream/AsyncIterator/Alternative) -- Ongoing processing of large data sets that do not fit in memory

Task 5

(Observable/EventEmitter/Alternative) -- Reactive message based communication between entities
