How to print the data of an array into a Google sheet with Google Apps Script

Question

So I have got this array that is called sourceData that contains elements and each element has 10 values so basically i want to print 252 rows and each row has a value in the cell (10 cells) starting from row 3. So what I did is that I created a for loop but its not working and its printing the week number "370" (which is the first value of the array) instead, and it was printed 503 times.

I also think that creating a for loop is going to take too long to print the data since there is a big number of data, so was wondering if there is a code that would be better than that one .

var sourceData =sourceData.sort(function(a,b){ return a[2] > b[2] ? 1 : -1; });
  sourceData = sourceData.reverse()
  
  for(let x=3; x<sourceData.length+3; x++){//   x is number of the row
  var y=0;
  thisSheet.getRange(parseInt(x),1 ,sourceData.length,10).setValue(sourceData[y]);
  y++;

I'm not gonna include the code how i got the sourceData since I dont think it's necessary

If you need more explanation please let me know.

Thank you.
