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

**Benchmark Overview**

The benchmark is comparing two approaches to iterate over an object in JavaScript: `_.each` from the Lodash library and the built-in `for...of` loop in ES6 (ECMAScript 2015).

**Options Compared**

* Lodash's `_each` function
* Built-in `for...of` loop with `Object.keys()` method

**Pros and Cons of Each Approach**

* **Lodash's `_each` function:**
	+ Pros:
		- Provides a convenient and flexible way to iterate over objects.
		- Can handle nested objects and arrays.
		- Often used in production code for its robustness and maintainability.
	+ Cons:
		- Adds an external dependency (Lodash library) that needs to be included.
		- May introduce overhead due to the additional function call.
* **Built-in `for...of` loop:**
	+ Pros:
		- No external dependencies required.
		- Optimized for performance and minimal overhead.
		- Native JavaScript implementation, which can lead to better browser support.
	+ Cons:
		- May require more boilerplate code (e.g., using `Object.keys()` to get the keys).
		- Less flexible than `_each` when dealing with complex iteration scenarios.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides a wide range of functions for common tasks, such as array manipulation, object transformation, and more. The `_each` function is one of its most useful helpers, allowing developers to iterate over objects in a concise and expressive way.

**Special JS Feature/Syntax: None**

There's no special JavaScript feature or syntax being used in this benchmark. It's purely focused on comparing two different iteration approaches.

**Other Alternatives**

If you need to iterate over an object without using `_each` or the `for...of` loop, other alternatives include:

* Using `forEach()` method on the object itself (e.g., `value.forEach(function(v) { ... })`)
* Implementing a custom loop using `while` or recursive functions
* Using other libraries like jQuery (which has its own iteration methods)

However, these alternatives may introduce additional dependencies or overhead, making them less suitable for this benchmark's specific use case.
