How to include Column K != null condition in google-apps-script?

Question

I have a code that copy pastes data from one sheet to another workbook whenever I run it. However, I only want specific data to copy from the original sheet where column K is not null. Could someone help recommend how I can incorporate that in my code?

Thanks in advance!

function transferList() 
{
   var sourceSheet = 
SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Colombo");
 var sourceData = sourceSheet.getDataRange().getValues();
 sourceData.splice(0,1);  // Remove header
 var targetSS = . 
SpreadsheetApp.openById("TargetSheetID").getSheetByName("Tester");
  var targetRangeTop = targetSS.getLastRow(); // Get # rows currently in target
 targetSS.getRange(targetRangeTop+1,1,sourceData.length,sourceData[0].length).setValues(sourceData);

}

You could iterate through your data and put all the values the have non-null column K into another array:

var targetData = [];
for (var i in sourceData) {
  if (sourceData[i][11] !== null && sourceData[i][11] !== '') {
    targetData.push(sourceData[i]);
  }
}

Then you'd paste targetData into your target sheet.
