Benchmark: Function vs reference

Script Preparation code:

function Animal() {
    this.type = "just an animal"
}

Animal.prototype.getType = function() {
  return this.type;
}

var animal = new Animal();

var out = "";

Tests:

1
for(var i = 0; i < 1000000; i++ ) { out = animal.getType(); }
2
for(var i = 0; i < 1000000; i++ ) { out = animal.type; }

Let's break down the provided JSON benchmark definition and test cases.

**Benchmark Definition**

The benchmark is defined as a JavaScript function that tests two different approaches to accessing an object property:

1. `animal.getType()`
2. `animal.type`

Both approaches are compared in terms of performance using the "for" loop, which iterates 1 million times.

**Options Compared**

There are two options being compared:

1. **Method 1:** `animal.getType()` - This approach uses a method call to access the `type` property.
2. **Method 2:** `animal.type` - This approach accesses the property directly without using a method call.

**Pros and Cons of Each Approach**

1. **Method 1 (method call):**
	* Pros:
		+ Can be more readable and maintainable, as it clearly separates concerns between data access and behavior.
		+ May be beneficial for polymorphism or overriding the property value in subclasses.
	* Cons:
		+ Can incur additional overhead due to method lookups or calls.
2. **Method 2 (direct access):**
	* Pros:
		+ Typically faster, as it bypasses method call overhead.
		+ May be more suitable for simple, constant properties.
	* Cons:
		+ Less readable and maintainable, as the property value is tied to its name.
		+ May lead to naming conflicts or unintended changes.

**Library and Purpose**

The `Animal` class uses a JavaScript library that allows it to represent an animal object with a type property. The purpose of this library is likely to provide a simple, concrete example for benchmarking the performance differences between method calls and direct property access.

**Special JS Feature or Syntax (None)**

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

**Other Alternatives**

If you wanted to modify or extend this benchmark, here are some alternatives:

1. **Use a different data structure**: Instead of using an `Animal` class, consider using an array or object with dynamic property names.
2. **Add more complex logic**: Introduce conditional statements, loops, or functions within the benchmarking code to increase its complexity and realism.
3. **Test with different browsers or platforms**: Expand the benchmark to include multiple browsers, operating systems, or devices to better simulate real-world usage scenarios.

Keep in mind that these alternatives would require additional modifications to the benchmark definition and test cases.
