let mass = [ 
  {"ip":"123","data":"2019-02-27 21:05:11","type":"1","source_id":123}, 
  {"ip":"123","data":"2019-02-27 21:07:37","type":"1","source_id":135}, 
  {"ip":"123","data":"2019-02-27 22:03:33","type":"1","source_id":123}, 
  {"ip":"123","data":"2019-02-28 22:06:00","type":"1","source_id":123} 
] 
 
console.log(group(mass)); 
 
function group(arr) 
{ 
let res = []; 
arr.forEach(el => { 
   if (res.length === 0)  
   { 
      el.total = 1; 
      res.push(el); 
   } 
   else { 
      res.every(elem => { 
        if (el.source_id === elem.source_id) 
        { 
          elem.total++; 
          return; 
        } 
        else { 
          el.total = 1; 
          res.push(el); 
        } 
      }); 
   } 
}); 
return res; 
} 
//console.log(res);
