// intial data
var source = {a:1,b:1,c:1,d:1,e:1,f:1,g:1,h:{a:-1,b:1,c:1,d:1,e:1,f:1,g:1}};
var source2 = {a:1,b:1,c:1,d:1,e:1,f:1,g:1,h:{a:-1,b:1,c:1,d:1,e:1,f:1,g:1}};

Tests:

Lodash
var result = _.isEqual(source, source2);
Ramda
var result = R.equals(source, source2);
Stringify
var result = JSON.stringify(source) === JSON.stringify(source2);

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

**Benchmark Overview**

The benchmark compares the performance of three approaches: Lodash, Ramda, and JSON.stringify equality. The test creates two identical objects, `source` and `source2`, with some nested properties. The goal is to check if these objects are equal using each approach.

**Approaches Compared**

1. **Lodash**: Lodash is a popular utility library that provides functional programming helpers. In this benchmark, it's used for the `_isEqual` function.
2. **Ramda**: Ramda is another utility library that provides functional programming helpers, similar to Lodash. Here, it's used for the `R.equals` function.
3. **JSON.stringify Equality**: This approach uses the `JSON.stringify` method to compare the two objects. It converts both objects to strings and checks if they are equal.

**Pros and Cons of Each Approach**

1. **Lodash ( `_isEqual` )**:
	* Pros: Well-maintained, widely used, and easy to use.
	* Cons: Adds an extra dependency, as Lodash needs to be included in the test environment.
2. **Ramda ( `R.equals` )**:
	* Pros: Similar benefits to Lodash, with a focus on functional programming.
	* Cons: Another additional dependency, as Ramda needs to be included.
3. **JSON.stringify Equality**:
	* Pros: No additional dependencies required, as it only uses built-in JavaScript methods.
	* Cons: May not work correctly for nested objects with complex data structures.

**Library Descriptions**

1. **Lodash**: Lodash is a utility library that provides over 120 functions for tasks such as:
	* Array manipulation
	* Object manipulation
	* Function composition
	* String manipulation
	* and more...
2. **Ramda**: Ramda is another utility library that provides functional programming helpers, including:
	* `R.equals` (equals function)
	* `R.identity` (identity function)
	* `R.map` (map function)
	* `R.filter` (filter function)
	* and more...

**Special JS Features or Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark.

**Other Alternatives**

If you need to compare object equality without using Lodash or Ramda, you can use the built-in `===` operator in JavaScript, which will only work correctly for simple objects with no nested properties. For more complex cases, you can use a library like **JSONSchema**, which provides a way to define and validate JSON schema definitions.

In terms of alternatives to benchmarking libraries like MeasureThat.net, there are many online tools that allow you to run JavaScript benchmarks, such as:

* jsperf.com
* browserbench.org
* benchmarkjs.com

These tools often provide more features than MeasureThat.net, such as support for multiple browsers and platforms.
