Benchmark: create object or create function

Script Preparation code:

var count = 100000
function runCount(f) {
	for(i=0; i<count; i++){f()}
}

Tests:

create empty object
runCount(() => ( {} ));
create empty function
runCount(() => ( () => {} ));
create function returns object
runCount(() => ( () => ({}) ));
create object with 2 functions
runCount(() => ( { open: () => {}, close: () => {} } ));
create function returns object with 2 funcitons
runCount(() => ( () => ({ open: () => {}, close: () => {} }) ));

Let's break down what's being tested in this benchmark.

**Benchmark Definition**
The benchmark is defined by the script preparation code: `var count = 100000\r\nfunction runCount(f) {\r\n\tfor(i=0; i<count; i++){f()}\r\n}`. This code sets up a loop that will execute a provided function `f` 100,000 times.

**Benchmark Variations**
The benchmark has five test cases, each defining a different approach to creating and executing functions or objects:

1. **Create empty object**: `runCount(() => ( {} ));`
2. **Create empty function**: `runCount(() => ( () => {} ));`
3. **Create function returns object**: `runCount(() => ( () => ({}) ));`
4. **Create object with 2 functions**: `runCount(() => ( { open: () => {}, close: () => {} } ));`
5. **Create function returns object with 2 functions**: `runCount(() => ( () => ({ open: () => {}, close: () => {} }) ));`

**Options Compared**

Each test case is comparing the performance of different approaches to creating and executing functions or objects:

* Creating an empty object vs. creating an empty function
* Creating a function that returns an object vs. creating a function with an inner function
* Creating an object with multiple methods vs. creating a single function

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

1. **Empty Object**: Creates an object, but no execution is required.
	* Pros: Less overhead for the interpreter.
	* Cons: May incur additional overhead due to object creation.
2. **Empty Function**: Creates a function without any execution or return value.
	* Pros: No overhead for execution or return value.
	* Cons: May be seen as unnecessary or "dead" code.
3. **Function Returns Object**: Creates an object and immediately returns it from the function.
	* Pros: More efficient than creating an object and then executing a separate function to access its methods.
	* Cons: The returned object is not accessible outside the function scope.
4. **Object with 2 Functions**: Creates an object with multiple methods, each of which takes no arguments.
	* Pros: More realistic use case for objects in JavaScript.
	* Cons: May incur additional overhead due to method creation and execution.
5. **Function Returns Object with 2 Functions**: Similar to the previous test case, but with an inner function.
	* Pros: Still more efficient than executing separate functions or creating a new object.
	* Cons: The returned object is not accessible outside the function scope.

**Library Usage**

None of the benchmark tests explicitly use any external libraries. However, it's worth noting that `forEach` loop used in the `runCount` function is a built-in method in JavaScript, which may be optimized by the browser engine for performance reasons.

**Special JS Features or Syntax**
This benchmark does not use any special JavaScript features or syntax beyond what's commonly found in modern browsers. However, it's worth noting that some of these features (e.g., arrow functions, template literals) are supported by many browsers but may have different behavior or performance characteristics depending on the engine and version.

**Alternatives**

Other alternatives for benchmarking similar code could include:

* Using a different programming language or runtime environment to create similar workloads.
* Measuring performance using alternative metrics (e.g., CPU cycles, memory allocation).
* Creating more complex test cases that involve multiple loops, conditional statements, or other control flow constructs.
