Underscore to flatten nested array of parent/child objects
underscore.js
Solution
A simple and more readable way to do this is
var list = [];
_.each(data, function(item){
list.push(_.omit(item, 'children'));
list.push(_.flatten(_.pick(item, 'children')));
});
var result = _.flatten(list);
The result is
[{
"name": "Some Name",
"value": 1234
}, {
"name": "Another name",
"value": 3456
}, {
"name": "A third name",
"value": 9876
}, {
"name": "Omg Lazer Guns",
"value": 3333
}, {
"name": "PewPewPew",
"value": 4444
}]
Problem
I have an array of objects, where each object has a "children" property (example data below). I want to flatten parents/children into a single array, with each parent immediately followed by it's children. I've written the following using lo-dash / underscore, and it works when I have one and only one child for each parent: ``` _.flatten(_.zip(myArr, _.flatten(myArr, "children"))) ``` I know I can use something like _.each and build an object, just wondering if there's a snazzy way to do this using _. Example Data: ``` [{ name: "Some Name", value: 1234, children: [{ name: "Another name", value: 3456 }, { name: "A third name", value: 9876 }] }, { name: "Omg Lazer Guns", value: 3333, children: [{ name: "PewPewPew", value: 4444 }] }]; ```
