Let's break down the benchmark and its components.

Benchmark Definition

The benchmark consists of two individual test cases:

"Object hash": This test case calls the objectHash function from the object-hash library, passing in the window.data object as an argument.
"JSON.stringify": This test case calls the JSON.stringify function, also passing in the window.data object as an argument.

Options Compared

The two options being compared are:

Using a dedicated hashing library (object-hash)
Using the built-in Stringify method of JavaScript's native JSON API (JSON.stringify)

Pros and Cons

Object-Hash Library

Pros:

Purpose-built for performance: The object-hash library is optimized for speed, making it suitable for high-performance use cases.
Simplified usage: The library provides a simple interface for hashing objects, reducing code complexity.

Cons:

External dependency: Using an external library adds an additional dependency to the benchmark, which may not be desirable for some users.
Potential overhead: Including an extra file may introduce minor performance overhead due to HTTP requests and loading times.

JSON.stringify

Pros:

Native implementation: The JSON.stringify method is a built-in part of JavaScript's native API, eliminating the need for external dependencies.
Low overhead: Using the native method has negligible overhead compared to including an external library.

Cons:

Performance limitations: The JSON.stringify method may not be as optimized or efficient as a dedicated hashing library like object-hash.
Complexity: Implementing a custom hash function can add complexity and code maintenance burden for users.

Library Description

The object-hash library is a lightweight, purpose-built JavaScript library designed specifically for hashing objects. Its primary purpose is to provide fast and efficient object hashing capabilities, making it suitable for applications requiring high-performance data integrity checks or encryption.

Special JS Features/Syntax

In this benchmark, the following special JavaScript features are used:

The window.data object is defined in a separate script preparation code block.
The objectHash function from the object-hash library is called to perform the hashing operation.
The JSON.stringify method is used to create a JSON string representation of the input data.

These features and syntax are not specific to this benchmark, but rather common practices in JavaScript development.

Let's break down the benchmark and its components.

**Benchmark Definition**

The benchmark consists of two individual test cases:

1. **"Object hash"**: This test case calls the `objectHash` function from the `object-hash` library, passing in the `window.data` object as an argument.
2. **"JSON.stringify"**: This test case calls the `JSON.stringify` function, also passing in the `window.data` object as an argument.

**Options Compared**

The two options being compared are:

* Using a dedicated hashing library (`object-hash`)
* Using the built-in `Stringify` method of JavaScript's native JSON API (`JSON.stringify`)

**Pros and Cons**
