I have a question, is there a method in lodash for validate a key value ?

I have the nex object:

```
var obj = [
              { name:'A', active:false, quantity : null },
              { name:'B', active:false, quantity : null },
              { name:'C', active:true,  quantity : 4    },
              { name:'D', active:false, quantity : null },
              { name:'E', active:false, quantity : null }
          ];

```

What i want is, validate if quantity is different to null using a lodash method witout a loop.
