Benchmark: Object values vs _.values vs my-values

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.core.js"></script>

Script Preparation code:

function getValues(obj) {
   const t = [];
   for(var key in obj) { t.push(obj[key]); }
   return t;
}

Tests:

Object values
var a = { a: 1, b: 2, c: 3}; Object.values(a);
_.values
var a = { a: 1, b: 2, c: 3}; _.values(a);
my-values
var a = { a: 1, b: 2, c: 3}; getValues(a);

**Overview**

The provided JSON represents a benchmark test on MeasureThat.net, which compares the performance of three approaches to extract values from an object: `Object.values()`, `_` (Lodash) function `values()`, and a custom implementation `getValues()`. The test aims to evaluate the efficiency of these methods in different JavaScript environments.

**What is tested**

The benchmark tests the following:

1. **Object.values()**: This method was introduced in ECMAScript 2019 as a part of the standard language specification. It returns an array containing all own property values of a given object.
2. **_.values()**: This function is part of the Lodash library and returns an array of values from an object.
3. **getValues()**: A custom implementation that uses a `for...in` loop to push each value from the object into an array.

**Options compared**

The benchmark compares the performance of these three approaches:

* `Object.values()`
* `_`.values()
* `getValues()`

Each approach has its pros and cons:

* **Object.values()**: Pros:
	+ Fastest and most efficient way to extract values from an object.
	+ Part of the ECMAScript standard, making it widely supported.
	Cons:
	+ Only available in ECMAScript 2019 and later versions.
* **_.values()**: Pros:
	+ Widely used and supported due to its presence in Lodash library.
	+ Easy to use and understand for developers familiar with Lodash.
Cons:
	+ May introduce additional overhead due to the library's complexity.
* **getValues()**: Pros:
	+ Custom implementation, which can be optimized for specific use cases.
	Cons:
	+ May require more effort to implement correctly.
	+ Less efficient than `Object.values()` and `_`.values().

**Other considerations**

When choosing an approach, consider the following factors:

* Performance: If speed is critical, `Object.values()` is likely the best choice. For less performance-critical scenarios, `_`.values()` or `getValues()` might be acceptable.
* Maintainability: If code readability and maintainability are important, `_`.values()` with its concise syntax might be a better option.
* Compatibility: If you need to support older browsers or environments that don't have ECMAScript 2019 support, consider using `_`.values() or `getValues()`.

**Library usage**

In the benchmark, Lodash is used as the underlying library for the `_.values()` function. Lodash provides a wide range of utility functions and helps developers write more efficient and concise code.

**Special JS feature/syntax**

The benchmark uses ECMAScript 2019 syntax (`Object.values()`) and does not require any special JavaScript features or syntax beyond what is available in modern browsers.

I hope this explanation helps!
