you can .map , .reduce

var raw = {       productid: {         id: "123456-1234-1234-1234-123456789012",         type: "product",         name: "product"       }     },     flatten = _.map(raw, function(item, k){        return _.reduce(item, function(obj, val, key){             obj[[k,key].join('_')] = val;            return obj;         }, {});     }); console.log(flatten[0])
