Data:
var data = [

Code:
var fdr = [];
var fd = function(n) {
if (n.items) {
_.forEach(n.items, function (value){
fd(value);
});
}
fdr.push(n);
};
_.forEach(data, fd);
console.log(fdr);
Desired output:

text: Cat,
type: Item,
items: null
},
{
id: 12,
level: 2,
text: Chair,
type: Item,
items: []
},
{
id: 121,
level: 3,

Questions
The fd function in the code is what I have come up with. I believe there's a 'cleaner' way to do this, just can't think of something. Plus, the function return items object, render it circular object.
JsBin:

Is there a way to flatten object recursively with lodash or just plain JavaScript?.
