Question 1

How to create an infinite sequence with imlazy?

Accepted Answer

Use functions like `range` with `Infinity` as the end parameter, e.g., `range(1, Infinity)` generates positive integers lazily. Always pair with `take` to avoid infinite loops when consuming the iterable.

Question 2

imlazy vs Ramda: which is better for functional programming?

Accepted Answer

imlazy specializes in lazy, immutable iterables and ES2015 protocols, ideal for infinite sequences and memory efficiency. Ramda offers a broader set of general-purpose FP utilities but without built-in lazy evaluation for iterables.

Question 3

Does imlazy work with async iterables or await?

Accepted Answer

No, imlazy is designed for synchronous iterables only and lacks support for asynchronous iteration protocols. For async operations, you'd need to handle promises separately or use other libraries.

Question 4

How to convert an imlazy iterable to an array?

Accepted Answer

Use the spread operator `[...iterable]` or `Array.from(iterable)`, as shown in the README with `[...twoFourSix]`. Be cautious with infinite iterables to prevent memory issues.

Question 5

What's the performance impact of using imlazy compared to native JavaScript?

Accepted Answer

Benchmarks indicate imlazy is slower for common operations; for example, filter over arrays can be 10x slower. Use it where lazy evaluation benefits (like handling infinite data) outweigh performance costs.

Question 6

Can I use imlazy in React or frontend frameworks?

Accepted Answer

Yes, imlazy is a dependency-free JavaScript library that works in any ES2015+ environment, including frontend frameworks, as long as the runtime supports iteration protocols.

Question 7

How does imlazy handle debugging for complex iterables?

Accepted Answer

Invoke `String` on iterables to use the custom toString method, which displays a LISP-like representation with truncation for infinite sequences, making nested structures easier to inspect.
