Let's break down the provided benchmark and its options.

**Benchmark Overview**

The benchmark compares three approaches for accessing nested properties in an object:

1. **Lodash.get**: A function from the Lodash library that provides a safe way to access nested properties.
2. **Property dot notation**: Directly accessing a property using the `.` operator, e.g., `person.sub.subsub.en`.
3. **Own get coded manually**: A custom implementation of the "own get" method, which is used by JavaScript engines to access own properties.

**Options Comparison**

Here's an overview of each option:

1. **Lodash.get**:
	* Pros: Provides a safe way to access nested properties, handles null and undefined values, and is generally faster than manual implementations.
	* Cons: Requires including the Lodash library, which may add overhead.
2. **Property dot notation**:
	* Pros: Fast and efficient, as it only involves a single property lookup.
	* Cons: May throw errors if the nested properties don't exist, and can be brittle if the property names change.
3. **Own get coded manually**:
	* Pros: Native implementation that doesn't require any additional libraries or overhead.
	* Cons: Requires manual error handling for missing properties, which can lead to performance issues.

**Lodash Library**

The Lodash library is a popular utility belt for JavaScript that provides various functions and methods for tasks like array manipulation, object manipulation, and more. In this benchmark, the `_.get` function is used to access nested properties safely and efficiently.

**Own Get Method**

The "own get" method is a native feature of JavaScript engines that allows you to access own properties without the need for explicit property lookups or manual error handling. However, in this benchmark, we're using a custom implementation of the "own get" method instead of relying on the native engine optimization.

**Special JS Feature/Syntax**

There's no special JavaScript feature or syntax used in this benchmark beyond the standard ECMAScript syntax.

**Benchmark Results**

The latest benchmark results show that:

* The **Native** option (property dot notation) is the fastest, with approximately 11.5 executions per second.
* The **Own get** option has a slightly lower execution rate than Lodash.get and Native, but still faster than the latter.
* The **Lodash.get** option is slower than the other two options, likely due to the added library overhead.

**Alternatives**

If you're interested in exploring alternative approaches for accessing nested properties, some options include:

* Using a library like jQuery or MooTools that provides similar functionality to Lodash.
* Implementing your own custom solution using JavaScript's built-in `in` operator and `hasOwnProperty` method.
* Using a different language or framework that provides native support for nested property access.

Keep in mind that these alternatives may have their own trade-offs in terms of performance, complexity, and feature set.
