Benchmark: JQuery.grep vs Array.filter

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js'></script>

Script Preparation code:

var array = [{id: "1", name: "1"}, {id: "2", name: "2"}, {id: "3", name: "3"}, {id: "4", name: "4"}, {id: "5", name: "5"}]
var needId = "3";

Tests:

$.grep
$.grep(array, function (element) { return element.id === needId; });
Array.filter
array.filter(function (element) { return element.id === needId; });

This benchmark compares two ways to find an element within an array: using jQuery's `$.grep` function and JavaScript's native `Array.filter` method.

**Options Compared:**

* **`$.grep(array, function (element) { return element.id === needId; })`**: This approach uses jQuery's `$.grep` function to filter the array. It takes two arguments: the array itself and a function that defines the filtering criteria. In this case, the function checks if an element's `id` property matches the desired `needId`.

* **`array.filter(function (element) { return element.id === needId; })`**: This approach utilizes the native `Array.filter` method available in JavaScript. It also takes two arguments: the array and a function that defines the filtering criteria. The function checks if an element's `id` property matches the desired `needId`.

**Pros and Cons:**

* **jQuery's `$.grep`**:
    * **Pros**:  Might be more familiar to developers who primarily use jQuery for DOM manipulation and event handling. 
    * **Cons**: Adds a dependency on the jQuery library, which increases the bundle size of your project. It can also introduce potential conflicts with other libraries that rely on jQuery's API.

* **`Array.filter`**:
    * **Pros**:  Native to JavaScript, so there are no external dependencies. More lightweight and efficient as it doesn't involve a separate library. Preferred for cleaner and more maintainable code.
    * **Cons**: Less familiar to developers who primarily focus on jQuery usage.

**Other Considerations:**

* In this specific case, both methods achieve the same outcome: finding the element with the matching `id`.  The choice between them often boils down to personal preference, project requirements (dependency on jQuery), and code readability.
* For more complex filtering scenarios or large datasets, the performance difference between these methods might become more noticeable.

**Alternatives:**

* **`findIndex()`**: This native JavaScript method returns the index of the first element in the array that satisfies the provided testing function. It's a concise alternative if you only need to find the *index* of the matching element.
* **`find()`**:  Similar to `findIndex()`, but it returns the actual element instead of just its index.

Remember that benchmarking results can vary depending on various factors like browser, hardware, and code execution environment.
