I'll provide an answer based on the provided data.

**Data**

* **Benchmark Data**: An array of objects containing benchmark definitions, test names, and raw UA strings for different JavaScript benchmarks.
	+ `_.partition`
	+ `lidash.partitionByKey`
	+ `_.partition` (Chrome 80, Desktop)
	+ `lidash.partitionByKey` (Chrome 80, Desktop)
* **RawUAString**: An array of Raw UA strings representing various browsers and devices.
* **Html Preparation Code**: A URL for a JavaScript library (`underscore.js`)
* **Individual Test Cases**: An array of objects defining individual test cases with benchmark definitions and test names.

**Question**

Given the provided data, what is the purpose of the `lidash.partitionByKey` benchmark?

**Answer**

The `lidash.partitionByKey` benchmark appears to be similar to a JavaScript implementation of the `_.partition` function. It takes an array, a key, and a value as inputs and returns two arrays: one containing elements that match the key-value pair and another containing elements that do not.

In this case, the `lidash.partitionByKey` benchmark is likely being used to compare its performance with the native JavaScript `_.partition` function. The raw UA strings provided suggest that both benchmarks are run on Chrome 80 and Desktop platforms.

To write this answer in the format of a single executable code block:
```javascript
function partitionKeyValue(arr, key, val) {
    return arr.reduce(
        (objKey, item) => ((item[key] === val ? objKey[0] : objKey[1]).push(item), objKey),
        [[], []]
    );
}

// Run the lidash.partitionByKey benchmark
var result = partitionKeyValue(data, 'family', 'CCP');

// Run the native JavaScript _.partition function for comparison
function _partition(arr, callback) {
    return arr.reduce(
        (objKey, item) => ((callback(item) ? objKey[0] : objKey[1]).push(item), objKey),
        [[], []]
    );
}

var resultNative = _partition(data, (item) => item.family === 'CCP');
```
