Benchmark: find vs some vs everygg

Tests:

some
const ss = [ {id:1, name:'test'}, {id:2, name:'test'}, {id:3, name:'test'}, {id:4, name:'test'}, {id:5, name:'test'}, {id:6, name:'test'}, {id:7, name:'test'}, {id:8, name:'test'}, {id:9, name:'test'}, {id:10, name:'test'}, ]; ss.some(item => item.id === 10);
every
const ss = [ {id:1, name:'test'}, {id:2, name:'test'}, {id:3, name:'test'}, {id:4, name:'test'}, {id:5, name:'test'}, {id:6, name:'test'}, {id:7, name:'test'}, {id:8, name:'test'}, {id:9, name:'test'}, {id:10, name:'test'}, ]; !ss.every(item => item.id !== 10)
find
const ss = [ {id:1, name:'test'}, {id:2, name:'test'}, {id:3, name:'test'}, {id:4, name:'test'}, {id:5, name:'test'}, {id:6, name:'test'}, {id:7, name:'test'}, {id:8, name:'test'}, {id:9, name:'test'}, {id:10, name:'test'}, ]; ss.find(item => item.id === 10);

**What is being tested?**

The provided JSON represents a set of JavaScript microbenchmarks that test the performance of different iteration methods in JavaScript: `find`, `some`, and `every`. Each benchmark definition specifies an array of objects and a callback function to filter or test these objects.

**Options compared**

There are three options being compared:

1.  **`find`**: uses the `Array.prototype.find()` method, which returns the first element in the array that satisfies the provided condition.
2.  **`some`**: uses the `Array.prototype.some()` method, which returns `true` if at least one element in the array satisfies the provided condition.
3.  **`every`**: uses the `Array.prototype.every()` method, which returns `true` if all elements in the array satisfy the provided condition.

**Pros and Cons of each approach**

*   **`find`**:
    *   Pros: efficient and concise way to find a single element that satisfies the condition.
    *   Cons: may return `undefined` if no such element is found, which can be unpredictable for performance measurements.
*   **`some`**:
    *   Pros: less memory-intensive than `find`, as it doesn't require finding the first matching element.
    *   Cons: returns `true` as soon as a matching element is found, so its performance may degrade if the array has many elements that don't match.
*   **`every`**:
    *   Pros: suitable for testing arrays with only one element, and it's more predictable than `some`.
    *   Cons: less efficient than `find`, as it requires checking all elements in the array.

**Library usage**

None of the provided benchmarks use any external libraries beyond standard JavaScript. The `Array.prototype` methods used (`find()`, `some()`, and `every()`) are part of the ECMAScript Standard, so they're widely supported across different browsers and environments.

**Special JS features or syntax**

There's no special JavaScript feature or syntax being tested in these benchmarks. They only use standard JavaScript syntax for array iteration methods.

**Other alternatives**

There are other ways to iterate over arrays in JavaScript that might be used in real-world scenarios, such as:

1.  **Loops**: using `for` loops or `while` loops to iterate over the array elements.
2.  **Map() and filter()**: applying `map()` and `filter()` methods to transform or filter the array without modifying its original structure.

These alternatives might be more suitable in specific use cases, but they can also introduce additional overhead compared to using `find()`, `some()`, or `every()`.

In summary, these benchmarks aim to compare the performance of different iteration methods for finding a single element (`find`), testing if any element satisfies a condition (`some`), and verifying that all elements satisfy a condition (`every`).
