Benchmark: some vs find on attribute

Tests:

find
let test = [{ id: 1, name: "effefefefe" }, { id: 2, name: "zf" }, { id: 3, name: "zzfefezf" }, { id: 4, name: "lol" }, { id: 5, name: "zefezf" }, ]; let bla = "lol"; let a = test.find(e => e.name === bla) !== null;
some
let test = [{ id: 1, name: "effefefefe" }, { id: 2, name: "zf" }, { id: 3, name: "zzfefezf" }, { id: 4, name: "lol" }, { id: 5, name: "zefezf" }, ]; let bla = "lol"; let a = test.some(e => e.name === bla) === true;
filter
let test = [{ id: 1, name: "effefefefe" }, { id: 2, name: "zf" }, { id: 3, name: "zzfefezf" }, { id: 4, name: "lol" }, { id: 5, name: "zefezf" }, ]; let bla = "lol"; let a = test.filter(e => e.name === bla) !== null;

**Benchmark Overview**

The provided benchmark measures the performance of three common array methods in JavaScript: `find()`, `some()`, and `filter()`.

**Methods Comparison**

1. **Find()**
	* Purpose: Returns the first element in an array that satisfies a provided testing function.
	* Example: `test.find(e => e.name === bla)`
	* Pros:
		+ Efficient when only one matching element is expected.
		+ Can be useful for finding the first occurrence of a specific value in an array.
	* Cons:
		+ May not find any elements if no match is found, which can lead to unexpected behavior.
		+ Can result in more computations if the testing function has side effects.
2. **Some()**
	* Purpose: Returns true if at least one element in an array satisfies a provided testing function.
	* Example: `test.some(e => e.name === bla)`
	* Pros:
		+ Efficient when checking for the presence of any matching elements.
		+ Can be used with side-effecting functions without performance issues.
	* Cons:
		+ May return true if no match is found, which can lead to unexpected behavior.
3. **Filter()**
	* Purpose: Creates a new array with all elements that pass the test implemented by a provided function.
	* Example: `test.filter(e => e.name === bla)`
	* Pros:
		+ Efficient when creating a new array with matching elements.
		+ Can be useful for filtering out specific values from an array.
	* Cons:
		+ May require more memory and computations if the filtering function has side effects.

**Library Usage**

None of the benchmarked methods rely on external libraries. They are built-in JavaScript methods that work natively with arrays.

**Special JS Features/Syntax**

There are no special JavaScript features or syntax mentioned in the provided benchmark definitions.

**Other Alternatives**

In addition to `find()`, `some()`, and `filter()`, other array methods that can be used for similar purposes include:

* **indexOf()**: Returns the index of the first element in an array that matches a specified value. If no match is found, it returns -1.
* **includes()**: Returns true if an array includes at least one element matching a specified value.

While these alternative methods exist, they are not explicitly mentioned in the benchmark definitions and may have different performance characteristics compared to `find()`, `some()`, and `filter()`.

**Benchmark Interpretation**

The latest benchmark results show that:

* `some()` has the highest execution rate (44929780.0 ExecutionsPerSecond) on Chrome 106, followed by `find()` (40511220.0), and then `filter()` (19435582.0).
* The differences in execution rates may be due to various factors such as the testing function's performance, array size, or browser-specific optimizations.

Keep in mind that benchmark results can vary depending on specific use cases and environments.
