How to get a column of a 2-dim array in GAS?

Question

How to extract a column of a 2-dim array in GAS? I thought I can do that if I transpose a 2-dim array, but is there an easy way of transposing a 2-dim array in GAS?

Answer 1

function getColumnTwo() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheetname');
const vs = sh.getDataRange().getValues();
const col2Values = vs.map(r => r[1]).flat();
