Ensuring the length of a Multidimensional Array

Today I decided to delve into coding with Google Sheets and JavaScript. As I was working on a project, I encountered a small issue:

function myFunction() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var data = sheet.getDataRange().getValues();

  for (var row = 1; row < data.length; row++) {
    If(data[row][0].length <= 0) { //Error Line
      Logger.log(data[row][0]);
    }
  }
}

I'm now getting an error saying that I'm missing a semicolon, but I can't figure out why. Any help on this would be greatly appreciated.

Answer №1

The reason for the error message indicating a `missing ;` is due to the typo in the "If" statement as highlighted by previous commentators. The JavaScript parser interprets `If(...)` as a function call followed immediately by `{`. This is incorrect; there should be a complete statement or a valid "if" condition before entering a block (`{ ... }`).
