Benchmark: ruse equal benchmark

Script Preparation code:

aobj = {hello: "hello"}
bobj = {world: "world"}

afunc = function() { return "hello"}
bfunc = function() { return "world"}

asym = Symbol("hello");
bsym = Symbol("world");

Tests:

func
afunc === bfunc
sym
asym === bsym
obj
aobj === bobj

Let's break down the provided JSON and explain what is tested, compared, pros/cons, and other considerations.

**Benchmark Definition**

The benchmark definition consists of three test cases:

1. `afunc === bfunc`: This test checks if two functions are equal using the `===` operator.
2. `asym === bsym`: This test checks if two symbols are equal using the `===` operator.
3. `aobj === bobj`: This test checks if two objects are equal using the `===` operator.

**Options Compared**

The benchmark compares three options:

1. **Object Reference Equality**: Using the `===` operator to compare objects for reference equality (i.e., checking if both variables point to the same object in memory).
2. **Reference Equality with a Weak Map**: Some JavaScript engines, like V8, optimize object comparison by using a weak map to cache references to objects. This test checks if this optimization is effective.
3. **Symbol Equality**: Using the `===` operator to compare symbols for equality.

**Pros/Cons of Each Approach**

1. **Object Reference Equality (using `===`)**:
	* Pros: Simple and widely supported, can be useful in certain scenarios where object reference equality matters.
	* Cons: Can lead to performance issues due to unnecessary memory allocations or checks.
2. **Reference Equality with a Weak Map**:
	* Pros: Optimized by V8 for improved performance, reduces unnecessary comparisons.
	* Cons: May not work as expected in all browsers or JavaScript engines.
3. **Symbol Equality (using `===`)**:
	* Pros: Can be faster than object reference equality since symbols are represented as primitive values.
	* Cons: Symbols are only available in ECMAScript 2015 and later, may not work with older browsers.

**Libraries and Special Features**

There is no explicit library mentioned in the benchmark definition. However, it's worth noting that JavaScript engines like V8 have their own optimizations and internal APIs for working with objects and symbols.

No special JavaScript features or syntax are used in this benchmark.

**Alternatives**

Other alternatives to test these scenarios might include:

1. Using a different comparison operator (e.g., `===` vs. `==`, or using `Object.is()` instead of `===`)
2. Comparing objects with a custom equality function
3. Testing symbol equality using other methods, such as `Symbol.prototype.toString()`
4. Comparing object references using techniques like "memoization" to cache previous results

These alternatives would require additional benchmark definitions and test cases to cover the desired scenarios.

I hope this explanation helps you understand what's being tested in this benchmark!
