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

Given

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

you can do it very easily with the lodash library:

var result = _.sum(obj);

If some of your values aren't numbers, you need to map them to numbers first:

var result = _.sum(_.map(obj, function(n){
     return +n;
     //or parseInt(n) or parseInt(n,10)
}));
