Benchmark: Lodash pick and native method 2

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var arr = [];
var object = { 
	type: 'aaa',
    foo: 'bar'
};
for (var i = 0; i <= 10; i++) { arr.push(object); }

Tests:

Lodash pick
arr.map(function (element) { return _.pick( element, 'type', 'subtype', 'card_last4', 'card_type', 'card_exp_month', 'card_exp_year', 'card_country', 'something' ); });
Native pick
function pick(object, keys) { return keys.reduce((obj, key) => { if (object && object.hasOwnProperty(key)) { obj[key] = object[key]; } return obj; }, {}); } arr.map(function (element) { return pick( element, ['type', 'subtype', 'card_last4', 'card_type', 'card_exp_month', 'card_exp_year', 'card_country', 'something'] ); });

Measuring performance is an essential task in software development, and MeasureThat.net provides a great platform for testing JavaScript microbenchmarks.

**Overview of the Benchmark**

The benchmark measures the performance difference between two approaches: using Lodash's `pick` function and implementing a custom `pick` function using only native JavaScript.

**Lodash's `pick` Function**

Lodash is a popular JavaScript utility library that provides various functions for tasks such as array manipulation, object creation, and more. The `pick` function in Lodash takes an object and an array of keys as arguments and returns a new object containing only the specified key-value pairs.

**Native Pick Function**

The native pick function uses only native JavaScript to achieve the same result as Lodash's `pick` function. It iterates through the provided array of keys, checks if each key exists in the input object, and adds it to the output object if it does.

**Comparison of Approaches**

Here are some pros and cons of each approach:

* **Lodash's `pick` Function:**
	+ Pros:
		- Faster execution time due to optimized native code.
		- Easier to use and more readable syntax.
		- Supports multiple platforms and browsers out-of-the-box.
	+ Cons:
		- Requires an additional library (Lodash) to be included in the project.
		- May have dependencies or conflicts with other libraries.
* **Native Pick Function:**
	+ Pros:
		- Faster execution time due to native code optimizations.
		- No external dependencies or libraries required.
		- Allows for more control over implementation details.
	+ Cons:
		- More complex syntax and harder to read.
		- May have platform-specific issues or compatibility problems.

**Other Considerations**

When choosing between these approaches, consider the following factors:

* **Performance**: If speed is a top priority, the native pick function might be a better choice. However, if you're working on a project with existing Lodash dependencies and don't need extreme performance optimization, using Lodash's `pick` function might be sufficient.
* **Readability and Maintainability**: For more complex projects or collaborative development environments, using Lodash's `pick` function can improve code readability and maintainability.
* **Platform and Browser Support**: If you're targeting multiple platforms or browsers, Lodash's `pick` function provides a convenient way to handle these differences.

**Library and Syntax Details**

The native pick function uses a similar syntax to Lodash's `pick` function but relies on native JavaScript to achieve the same result.
