Copying data from a sheet to another with conditions - google-apps-script

Question

I have been trying to copy some data from a sheet to another but I have been running into some trouble.
I have to copy data and stop copying until the scripts finds an empty space, and I have to paste this data into another sheet where there's blank space (available space).
This is the code I have so far:
function copyInfo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("sheet1");
var pasteSheet = ss.getSheetByName("sheet2");
var source = copySheet.getRange(11,1,1,10);
var destination = pasteSheet.getRange(1,1,1,10);
for (i = 1; i < 20; i++) {
if (destination.isBlank() == true) {
destination = pasteSheet.getRange(i, 1, 1, 10);
source = copySheet.getRange(i + 10, 1, 1, 10);
source.copyTo(destination);
} else {
destination = pasteSheet.getRange(i, 1, 1, 10);
}
}
}
It recognizes that the destination has an empty space, although it doesn't really paste it. The for (i = 1; i <20; i++) is for testing purposes.

If your data doesn't have any blank rows in between the first row and last non-empty row, then you can use this:
Sample Data:
sheet1
sheet2
Script:
function copyInfo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("sheet1");
var pasteSheet = ss.getSheetByName("sheet2");
// get last rows of each sheet
var sLastRow = copySheet.getLastRow();
var dLastRow = pasteSheet.getLastRow();
// get data from sheet1 from row 11 to last row
var source = copySheet.getRange(11,1,sLastRow - 10,10).getValues();
// paste data to sheet2's last row
pasteSheet.getRange(dLastRow + 1,1,source.length,source[0].length).setValues(source);
}
Output:
Alternative:
If you have blank rows in between your sheet1, you can filter the values in sheet1.
Sample Data:
blank row 13 in sheet1
function copyInfo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var copySheet = ss.getSheetByName("sheet1");
var pasteSheet = ss.getSheetByName("sheet2");
// get last rows of each sheet
var sLastRow = copySheet.getLastRow();
var dLastRow = pasteSheet.getLastRow();
// get data from sheet1 from row 11 to last row
// exclude rows with blank values in all columns
var source = copySheet.getRange(11,1,sLastRow - 10,10).getValues()
.filter(row => row.filter(col => !col).length < row.length);
// paste data to sheet2's first blank row
pasteSheet.getRange(dLastRow + 1,1,source.length,source[0].length).setValues(source);
}
Output:
