**What is being tested**

MeasuringThat.net provides a platform for comparing the performance of different JavaScript microbenchmarks. In this case, two test cases are being compared: `lodash.each` and `Object.forEach`. The benchmark being measured is the execution time of a loop that iterates over an array using each of these methods.

**Options compared**

The main options being compared are:

1. **_.each**: This is the Lodash implementation of the `.each` method, which applies a function to each element in an array.
2. **Object.forEach**: This is the built-in `forEach` method on arrays in JavaScript, which also applies a function to each element in an array.

**Pros and Cons**

**_.each (Lodash)**

Pros:

* Lodash is a widely-used library that provides a robust set of utilities for functional programming.
* The implementation of `.each` is likely to be optimized for performance.

Cons:

* It adds extra overhead due to the use of a external library.
* There may be potential issues with caching or memoization.

**Object.forEach (Native JavaScript)**

Pros:

* This is the native implementation of `forEach` in JavaScript, which means it's typically faster and more efficient than a third-party library.
* No additional overhead due to using an external library.

Cons:

* May not provide all the same features as Lodash's `.each`, such as handling edge cases or supporting iterators.

**Other considerations**

When choosing between `_.each` and `Object.forEach`, consider the following factors:

* Performance: If speed is critical, `Object.forEach` might be a better choice. However, if you need additional functionality beyond basic iteration, Lodash's `.each` might be more suitable.
* Code readability: Some developers prefer the explicitness of `Object.forEach`, while others find it less readable due to its reliance on the array prototype.
* Maintainability: If you're using a third-party library like Lodash, you'll need to manage dependencies and potential updates.

**Library usage**

The test case uses Lodash's implementation of `.each`. The purpose of this library is to provide a comprehensive set of utility functions for functional programming in JavaScript. In this specific benchmark, it provides an optimized implementation of the `.each` method that can be used instead of the native `forEach` method.

**Special JS feature or syntax**

There doesn't appear to be any special JavaScript features or syntax being used in these benchmarks. The tests focus on measuring the performance difference between two common iteration methods.
