Benchmark: search string by include vs index of

Script Preparation code:

var searchStrings = ["hello", "world", "Benchmarks"]
var rawString = "https://www.measurethat.net/Benchmarks/Add/hello/world";

Tests:

use some
var temp = searchStrings.some(x => rawString.includes(x));
use indexOf
var temp = rawString.indexOf("hello") === -1 && rawString.indexOf("/world") === -1 && rawString.indexOf("test") === -1

Let's dive into explaining the provided benchmark.

**What is being tested?**

MeasureThat.net is testing two different approaches for searching a string within another string:

1. **Using `some()`**: This approach checks if any of the elements in the `searchStrings` array satisfy the condition that the `rawString` includes the element.
2. **Using `indexOf()`**: This approach checks if the `rawString` contains the specified strings by checking their index.

**Options compared**

The two options being compared are:

* Using `some()` with a callback function to check for inclusion
* Using `indexOf()` with explicit string comparisons

**Pros and Cons of each approach:**

* **Using `some()`**:
	+ Pros:
		- More concise code
		- Can handle multiple strings, reducing the need for nested loops
	+ Cons:
		- May be less efficient due to the use of a loop within the callback function
		- Can be slower if the `searchStrings` array is large
* **Using `indexOf()`**:
	+ Pros:
		- Typically faster than using `some()`
		- More explicit and predictable results
	+ Cons:
		- Requires separate calls for each string, increasing code complexity
		- May not handle edge cases (e.g., null or undefined strings) as well as `some()` might

**Library usage**

In this benchmark, the `some()` function is used from the JavaScript standard library. It's a built-in method that allows you to check if any elements in an array satisfy a condition.

**Special JS feature or syntax**

There are no special features or syntax being tested in this benchmark. The focus is on comparing two different approaches for searching strings within another string.

Now, let's talk about other alternatives:

* **Using `includes()`**: This method was introduced in ECMAScript 2019 and provides a more concise alternative to `indexOf()`. It would be an interesting addition to the benchmark if MeasureThat.net were to include it.
* **Regular expressions**: Another approach to searching strings within another string is using regular expressions. This could provide an additional comparison option for the benchmark.

In summary, this benchmark compares two approaches for searching a string within another string: using `some()` and using `indexOf()`. The results show that both methods have their trade-offs in terms of performance and code complexity.
