I found the benchmark mentioned in the article - here's the part comparing map: https://funkia.github.io/list/benchmarks#map https://funkia.github.io/list/benchmarks#map Apparently, List is ~3x faster than native array.map, with the difference increasing with the number of elements. I see that random access and iterator are two operations where native array is fastest.
