10. Lazy Collections

Lazy Collections

Fast and lazy collection operations

---

Working with methods like .map(), .filter() and .reduce() is nice however they create new arrays and everything is eagerly done before going to the next step.

This is where lazy collections come in, under the hood we use iterators and async iterators so that your data flows like a stream to have the optimal speed.

All functions should work with both iterator and asyncIterator, if one of the functions uses an asyncIterator (for example when you introduce delay(100)), don't forget to await the result!

let program = pipe(
  map(x => x * 2),
  filter(x => x % 4 === 0),
  filter(x => x % 100 === 0),
  filter(x => x % 400 === 0),
  toArray()
);
program(range(
