Great article. Seems like lazy sequences do similar things to transducers. How are they different?

I believe a transducer could be a feature of a lazy sequence. But a lazy sequence does not guarantee the process is using a transducer.

I just checked lazy.js and it seems like it does support this.

lazy.js quote:

What’s important here is that no iteration takes place until you call each, and no intermediate arrays are created. Essentially Lazy.js combines all query operations into a sequence that behaves quite a bit like the procedural code we wrote a moment ago. (If you ever do want an array, simply call toArray on the resulting sequence.)
