Benchmark: Intersect test - MeasureThat.net

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.9.0/underscore.js"></script>

Script Preparation code:

var data = ["ocpp1.6", "ocpp2.0", "ocpp3.0"]
var target = ["ocpp1.6"]

Tests:

underscore
const supportedProtocols = _.intersection(target, data) const returnedProtocol = !supportedProtocols.length ? 'ocpp1.6' : _.first(supportedProtocols)
non-underscore
const returnedProtocols = target.length ? 'ocpp1.6' : target.find((protocol) => data.includes(protocol)) || 'ocpp1.6'

Let's break down the provided benchmark JSON and its test cases.

**Benchmark Definition:**

The benchmark definition is a set of rules that govern how the benchmark will be executed. It defines two test cases:

1. **"Intersect test"**: This is the name of the benchmark, and it has no description.
2. **"Script Preparation Code"**: The script preparation code is a JavaScript snippet that sets up some data for the benchmark. In this case, `data` contains an array of strings with different OCPP versions (`ocpp1.6`, `ocpp2.0`, `ocpp3.0`), and `target` also contains an array with only one string, `ocpp1.6`.
3. **"Html Preparation Code"**: The HTML preparation code is a snippet that includes a reference to the Underscore.js library.
4. **"Benchmark Definition"**: This section defines two test cases:
	* **Test Case 1: "underscore"**: This test case uses the Underscore.js library's `intersection` function to find the common elements between `target` and `data`.
	* **Test Case 2: "non-underscore"**: This test case doesn't use the Underscore.js library. Instead, it manually checks if there are any matches between `target` and `data` using the `find` method.

**Options Compared:**

The benchmark compares two approaches:

1. Using the `intersection` function from the Underscore.js library to find common elements between `target` and `data`.
2. Not using the `intersection` function, instead manually checking for matches using the `find` method.

**Pros and Cons:**

Using the `intersection` function has some pros:

* It's a concise way to find common elements between two arrays.
* It's likely to be faster than manual iteration because it uses optimized algorithms under the hood.

However, there are also some cons:

* It requires including an external library (Underscore.js) which might introduce additional overhead.
* If the library is not available or not properly loaded, the benchmark may fail.

Not using the `intersection` function has its own pros and cons:

Pros:

* No additional library dependency is required.
* The code is more straightforward and easier to understand.

Cons:

* Manual iteration can be slower than using a optimized algorithm like `intersection`.
* The code is more verbose and might require more error-prone steps.

**Library:**

The Underscore.js library is a popular utility function library for JavaScript. It provides various functions for tasks such as array manipulation, string templating, and functional programming. In this benchmark, the `intersection` function is used to find common elements between two arrays.

**Special JS Features/Syntax:**

There are no special JavaScript features or syntax used in these test cases. The code uses standard JavaScript constructs like arrays, loops, and conditional statements.

Now, let's talk about alternatives:

If you don't want to use the Underscore.js library, you can also implement a manual solution using a loop to find common elements between `target` and `data`. Another approach could be using the `filter` method in combination with the `some` method to achieve the same result.

For example:
```javascript
const returnedProtocol = target.filter((protocol) => data.includes(protocol)).length ? protocol : 'ocpp1.6';
```
Keep in mind that this implementation might not be as efficient as using the `intersection` function from Underscore.js, but it's a viable alternative if you don't want to include an external library.
