Benchmark: Get object 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:

var a = {'a': 1, 'b': 2}
var b = [1, 2]

Tests:

Object.values
Object.values(a)
Lodash
_.values(a)
For loop
var c = [] for(const key in a) { c.push(a[key]) } c

Let's break down the benchmark and explain what's being tested.

**Benchmark Definition**

The benchmark is defined by two types of code: script preparation code and HTML preparation code. The script preparation code is executed once, before running the actual benchmark tests. In this case, it creates an object `a` with properties `'a'` and `'b'`, and an array `b`. This setup ensures that all test cases have access to these variables.

The HTML preparation code includes a link to the Lodash library, which is used in one of the test cases.

**Individual Test Cases**

There are four test cases:

1. **Object.values**: Tests the built-in JavaScript method `Object.values()` on object `a`.
2. **Lodash**: Tests the `_values()` function from the Lodash library.
3. **For loop**: Tests an alternative implementation using a for loop to iterate over object `a` and push its values into an array `c`.
4. **Return array**: Tests that simply returning the array `b` is fast enough.

**Options Compared**

The test cases compare different approaches:

* Built-in JavaScript method (`Object.values()`) vs. Lodash library (`_values()`).
* For loop implementation vs. direct function call (returning an array).

**Pros and Cons of Each Approach**

1. **Built-in JavaScript method (`Object.values()`) vs. Lodash library (`_values()`)**:
	* Built-in: No external dependency, easier to understand, but might be slower due to language overhead.
	* Lodash: Faster, more efficient, and widely used, but requires an additional library import.
2. **For loop implementation vs. direct function call**:
	* For loop: More readable, familiar syntax, but potentially slower due to iteration overhead.
	* Direct function call: Faster, more concise, but less readable.

**Other Considerations**

The benchmark also measures the impact of device platform (Desktop) and operating system (Mac OS X 10.14.6). This suggests that the test is not just focused on JavaScript performance but also on browser and hardware-specific aspects.

As for special JS features or syntax, none are mentioned in this specific benchmark.

**Alternatives**

Other approaches to achieve similar results could include:

* Using `for...in` instead of `Object.values()` for a more traditional for loop implementation.
* Utilizing other libraries like Moment.js or Underscore.js for array manipulation.
* Implementing custom iteration logic using `forEach()` or `map()`.
* Using a different data structure, such as an object with numerical properties.

Keep in mind that these alternatives might not provide the same level of performance as the built-in JavaScript method or optimized libraries like Lodash.
