Sum all properties in object

Question

I have the following object:

{\"speed\":299,\"equipment\":49,\"teleabb\":49,\"additional\":50,\"optional\":\"299\"}

I want to sum all this

Answer 1

Using Lodash:

var obj = {"speed":299,"equipment":49,"teleabb":49,"additional":50,"optional":"299"};

var val = _.sumBy(_.values(obj), function(v) {
   return parseInt(v)
});
