    "km:header": {
      "km:range": "potato"
    }
  }
};

function deepPick(json, ...keys) { return keys.reduce((obj, key) => {
                                        if (!obj) return;

                                        if (obj[key]) {
                                            return obj[key];
                                        }
                                    }, undefined);
                                 }

Tests:

Lodash
_.get(testObject, ['km:acc', 'km:header', 'km:range']);
Reduce
deepPick(testObject, 'km:acc', 'km:header', 'km:range')

**Benchmark Overview**

MeasureThat.net is a platform for comparing the performance of JavaScript libraries and built-in functions in various browsers. In this case, we're benchmarking two approaches: `_.get` from Lodash and `deepPick` using the Reduce function.

**Library Explanation**

* **Lodash**: A popular utility library for JavaScript that provides a wide range of helper functions to simplify tasks such as array manipulation, object iteration, and more. `_get` is a specific function in Lodash that allows you to dynamically access nested properties in an object.
* **Reduce**: A built-in JavaScript function that applies a given callback function to each element of an array (or array-like object) in turn, accumulating a result.

**Options Being Compared**

The benchmark compares the performance of two approaches:

1. `_.get` from Lodash: This approach uses the `_.get` function from Lodash to dynamically access the nested properties in the `testObject`.
2. `deepPick` using Reduce: This approach defines its own `deepPick` function that uses the Reduce function to iterate through the object's properties and return a value.

**Pros and Cons of Each Approach**

* **_.get from Lodash**: Pros:
	+ Provides a more elegant and concise way to access nested properties.
	+ Less error-prone, as it's designed to handle missing properties.
*   Cons:
    + Requires including an additional library (Lodash).
    + Might incur overhead due to the extra function call.
* **deepPick using Reduce**: Pros:
    + Built-in JavaScript function, so no additional libraries are required.
    + Can be more lightweight than using a separate library.
*   Cons:
    + Requires defining and implementing the `deepPick` function manually.
    + May lead to errors if not implemented correctly.

**Special JS Feature or Syntax**

In this benchmark, there's no explicit usage of special JavaScript features like async/await, Promises, or modern syntax (e.g., arrow functions). The code is written in traditional style.

**Other Alternatives**

If you're interested in exploring other approaches, consider:

* Using the `in` operator to access properties directly: `testObject['km:acc']['km:header']['km:range']`
* Implementing a custom `deepPick` function using recursion or another approach
* Utilizing other utility libraries (e.g., Immutable.js, Ramda) that provide similar functionality

Keep in mind that the choice of approach depends on your specific use case and performance requirements.
