Benchmark: JSON.stringify vs recursive for-loop

Script Preparation code:

const tree = [{
        'title': "some title",
        'channel_id': '123we',
        'options': [{
            'channel_id': 'abc',
            'image': 'http://asdasd.com/all-inclusive-block-img.jpg',
            'title': 'All-Inclusive',
            'options': [{
                'channel_id': 'dsa2',
                'title': 'Some Recommends',
                'options': [{
                    'image': 'http://www.asdasd.com',
                    'title': 'Sandals',
                    'id': '1',
                    'content': {}
                }]
            }]
        }]
    },

Tests:

JSON.stringify
function findNestedObj(root, ID) { let item; JSON.stringify(root, (_, obj) => { if (obj && obj.id === ID) { item = obj; } return obj; }); return item; }; const result = findNestedObj(tree, '2');
recursive for-loop
function findNestedObj(root, ID) { let item; for (let i = 0; i < root.length && !item; i += 1) { if (root[i].id === ID) { item = root[i]; return item; } if (root[i].options) { item = findNestedObj(root[i].options, ID); if (item) return item; } } return item; }; const result = findNestedObj(tree, '2');
