Even with gsheet v2.1, users make mistakes. Here are the top three and their solutions.

function getLastDataRow(sheet, column = 1) 
  const values = sheet.getRange(1, column, sheet.getMaxRows()).getValues();
  for (let i = values.length - 1; i >= 0; i--) 
    if (values[i][0] && values[i][0].toString().trim() !== "") return i + 1;
return 0;

One of the most celebrated features of the gsheet v2.1 framework is the batchUpdate method. Instead of modifying cells one by one, you build a single payload.

// GSheet v2.1 batch write example
const updates = [
   range: "A2:A100", values: [[timestamp], [timestamp2], ...] ,
   range: "B2:B100", values: [["Completed"], ["Pending"], ...] 
];
sheet.batchUpdate(updates);

Performance gain: Up to 40x faster for large datasets (10,000+ cells).
