What's the modern performant way to parse tab-tab-return data into an array of rows, each containing an array of column values. No quotes or funny chars involved, i.e., no tabs or returns within individual "cells" just straight up numbers, letters, hyphen, underscore, space. Old-school version is nested listToArray() calls. Is there a slicker and/or faster way?

still old school but with a twist https://trycf.com/gist/1784637c56db17e27102db6179d8ba70/acf2021?theme=monokai

NB: don't need the braces and the return if there's only a return value. So poss just:

newData = data.listToArray(chr(10)).map((row) => row.listToArray(chr(9)))

well with 7 billion of us I can't guarantee that but they came from a random data generator
