If the following is true then you don't have duplicates: `data.length === new Set(data.map(d=>d.Tid)).size` — HMR, Feb 11 '19 at 14:00
If the following is true then you **don't** have duplicates, if it shows false then you do have duplicates. — HMR, Feb 11 '19 at 14:03

Something like this should do it:

array.forEach(function(e,i){
  for (var j = i+1; j < array.length; j++) {
     if (e.Tid == array[j].Tid) {
        // ids match, do something
     }
   }
 });
