Google Apps Script - How to copy a column(s) to another sheet at next available column

Question

I have a requirement where I need to take values from one column (or more) and copy them to another sheet in the next available column (s). I have written a script like this

Answer 1

The entire 4th column & 17th row onward can be appended as a column into a different sheet with this approach also.

  var sheetfrom = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('sheetfrom');
  var sheetto = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('sheetto');

  sheetfrom.getRange(17, 4, sheetfrom.getLastRow(), 1).copyTo(sheetto.getRange(1, 
  sheetTo.getLastColumn()+1, sheetfrom.getLastRow()-17, 1), {
    contentsOnly: true
  });

This also overcomes the empty cell problem of copying data from some Formula outputs.
