Google App Script looping through array of values

Question

Hello I'm trying to loop through an array of values and If the any of the values is bigger than 0, then the script should send a specific email. I just cant figure it out how to do it. What am I doing wrong?

  var TO = ['email1@gmail.com','email2@gmail.com'];
  var failedOperation = [0, 0, 0, 52, 2, 5,]
  var message1 = 'Check the sheet';
  var message2 = 'Its Ok';
  var subject = 'Your Google Spreadsheet Alert';

  for(var i in failedOperation && var j in TO){
    if(typeof failedOperation[i] > 0){
      MailApp.sendEmail(TO[j], subject, message1);
    }
    else{
      MailApp.sendEmail(TO[j], subject, message2);
    }
  }

function www() {
  var TO = ['email1@gmail.com','email2@gmail.com'];
  var failedOperation = [0, 0, 0, 52, 2, 5];
  var message1 = 'Check the sheet';
  var message2 = 'Its Ok';
  var subject = 'Your Google Spreadsheet Alert';
  for(var i=0; i<failedOperation.length;i++){
    if(failedOperation[i]>0){
      MailApp.sendEmail(TO[1], subject, message1);
    }else{
      MailApp.sendEmail(TO[0], subject, message2);
    }
  }
}
