Add date and text at the last row after a copy paste - google-apps-script

Question

I'm breaking my head here trying to figure it out a way to achieve this in a simples way.
I got working a code that copies a range from a sheet and paste in another at the last row.
function copyInfo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("Review");
var pasteSheet = ss.getSheetByName("Log");
// get source range
var source = copySheet.getRange(3,2,15,5);
// get destination range
var destination = pasteSheet.getRange(pasteSheet.getLastRow()+1,3,15,5);
// copy values to destination range
source.copyTo(destination, SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
}
The problem is, at the destination sheet, I still have columns A and B empty. By each row in the source (varies from time to time) copied, I need to place at column A todays date and column B the text "Review".
Like: Date (column A) | Revview (column B) | Pasted Data from Source (column C and other)
Do I need to write a completely new code to check for empty or can I implement both solutions into this code?

Answer 1

The code should fill the two cells before your data. It also caters for the setup where you have three areas in the same sheet.
Each copyInfoXd_button function will be assigned to your button image.
function copyInfo1d_button() {
copyInfo(2, "B1:B");
}
function copyInfo7d_button() {
copyInfo(9, "I1:I");
}
function copyInfo30d_button() {
copyInfo(16, "P1:P");
}
function copyInfo(startingCol, subjectCol)
{
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("Review");
var pasteSheet = ss.getSheetByName("Log");
const sourceCols = 4; //actual number of columns to copy, not including the empty column H
const destCols = 6; //actual number of columns to write to, from DATE to OBS
//find the last row from a colum
var avals = copySheet.getRange(subjectCol).getValues();
var lastRow = avals.filter(String).length;
var rowsToCopy = lastRow - 2; //skip the first 2 rows as they are headers
// get source range
var source = copySheet.getRange(3,startingCol,rowsToCopy,sourceCols); // row, column, number of rows and number of columns
// get destination range
var destination = pasteSheet.getRange(pasteSheet.getLastRow()+1,1,rowsToCopy,destCols);
var data = [];
var sourceValues = source.getValues();
//construct new data for the destination range
for (var row in sourceValues) {
var destRow = [Utilities.formatDate(new Date(), ss.getSpreadsheetTimeZone(), 'MMMM dd, yyyy'), 'Review'];
destRow = destRow.concat(sourceValues[row]);
data.push(destRow);
}
destination.setValues(data);
}

Answer 2

I made it! I'm so proud! Thank you all for the help!
I'm beginning to do stuff like this!
After the Charles answer I looked for a way to add to each row. However, I know the code might not be too elegant, and I couldn't figured it out a way of doing using script itself, so I added a helper cell inside the sheet in H1 and H2.
Here's the solution:
function copyInfo24() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("Review");
var pasteSheet = ss.getSheetByName("Log");
// get source range
var source = copySheet.getRange(4,2,99,5);
// get destination range
var destination = pasteSheet.getRange(pasteSheet.getLastRow()+1,3,99,5);
// copy values to destination range
source.copyTo(destination, SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);
// Sets date at Column A and "Review" at Column B.
var data = [];
for(var i =0; i < copySheet.getRange("H1").getValue(); i++) {
data.push([Utilities.formatDate(new Date(), ss.getSpreadsheetTimeZone(), 'MMMM dd, yyyy'), 'Review']);
}
reviewRange = pasteSheet.getRange(pasteSheet.getLastRow()-copySheet.getRange("H2").getValue(), 1, copySheet.getRange("H1").getValue(), 2)
reviewRange.setValues(data); //set the date and 'Review' data
}
