Remove item from object that does not have value

I do not want to render a label if it does not have a value.

Object { equip1: "888" equip2: "" equip3: "" equip4: "" equip5: "" equip6: "" equip7: ""}

Template:

 <% var equipment = data.equipData                      
_.each(equipment, function(numUnits, equipName){%>
  <tr>
   <td><label for="equipCatagory">{{equipName}}</label></td>
   <td>{{numUnits}}</td>
 </tr>
 <% }) %>

What is the best way to not show a label if numUnits is empty?

You need to add a condition to the _.each callback function:

 <% var equipment = data.equipData                      
_.each(equipment, function(numUnits, equipName){
if(!numUnits) return;
%>
  <tr>
   <td><label for="equipCatagory">{{equipName}}</label></td>
   <td>{{numUnits}}</td>
 </tr>
 <% }) %>
