lodash property search in array and in nested child arrays

Question

I have this array:

[
    {
        id: 1,
        name: \'test 1\',
        children: []
    },
    {
        id: 2,
        name: \'test 2\',
        childr         


        

Answer 1

Another lodash option with children key and unlimited levels deep.

const flattenItems = (items, key) => {
    return items.reduce((flattenedItems, item) => {
        flattenedItems.push(item)
        if (Array.isArray(item[key])) {
            flattenedItems = flattenedItems.concat(flattenItems(item[key], key))
        }
        return flattenedItems
    }, [])
}

const item = find(flattenItems(items, 'children'), ['id', 4])
