javascript - NodeJS Count how many objects in array? -

How can I count how many objects are inside the array?

looks like an array:

  [{id: 1}, {id: 2}, ...]  

< P> I think I can use counting () if it was PHP, but what about NODJS / Javascript?

Edit:

  if (offer.items_to_receive.length & gt; 0) {console.log ("item:" + offer.items_to_receive.length); (Var i = 0; i  

How can it read "worth X tickets", but not the other part?

use

  var data = [{id: 1} , {Id: 2}]; Console.log (data.length);      
  Update , in my edit, I think  
  offer .items_to_receive  is  undefined , make sure the object  proposal  is the property  items_to_receive  (should be array);
