It seems like you're trying to prepare some test data for benchmarking. I'll help you parse and format the data. Here's the parsed data: **Objects** 1. `obj1`: ```json { "id": "5005", "type": "Sugar" }, { "id": "5007", "type": "Powdered Sugar" }, { "id": "5006", "type": "Chocolate with Sprinkles" }, { "id": "5003", "type": "Chocolate" }, { "id": "5004", "type": "Overwritten" } ``` 2. `obj2`: ```json { "id": "0002", "type": "Overwritten", "name": "Raised", "ppu": 0.55, "batters": { "batter": [ { "id": "1001", "type": "Overwritten" } ] }, "topping": [ { "id": "5001", "type": "None" }, { "id": "5002", "type": "Overwritten" }, { "id": "5005", "type": "Sugar" }, { "id": "5003", "type": "Chocolate" }, { "id": "5004", "type": "Maple" } ] } ``` 3. `obj3`: ```json { "id": "0003", "type": "Overwritten", "name": "Old Fashioned", "ppu": 0.55, "batters": { "batter": [ { "id": "1001", "type": "Overwritten" }, { "id": "1002", "type": "Chocolate" } ] }, "topping": [ { "id": "5001", "type": "None" }, { "id": "5002", "type": "Glazed" }, { "id": "5003", "type": "Chocolate" }, { "id": "5004", "type": "Maple" } ] } ``` **Individual Test Cases** 1. `Lodash.merge(obj1, obj2)` 2. `deepmerge(obj1, obj2)` **Latest Benchmark Result** 1.
