Benchmark: Method vs Function

Script Preparation code:

class Calculator {
  add(value) {
    return value + 1;
  }
}

var calculator = new Calculator();

function add(value) {
  return value + 1;
}

Tests:

Method
calculator.add(10);
Function
add(10);

I'll break down the provided benchmark definition and test cases to explain what's being tested, compared, and considered.

**Benchmark Definition:**

The benchmark defines two different approaches for adding 1 to a value: using a `method` (an instance method of an object) and using a `function`. The script preparation code provides an example class `Calculator` with an `add` method, as well as a standalone function `add`.

**What's being tested:**

The benchmark measures the performance difference between these two approaches:

1. **Method**: Invoking the `add` method on an instance of the `Calculator` class.
2. **Function**: Calling the standalone `add` function directly.

**Options Compared:**

The comparison focuses on the performance aspects of these two approaches. The benchmark aims to determine which one is faster, assuming that both implementations are identical except for the way they're invoked (method call vs. function call).

**Pros and Cons:**

1. **Method**: Pros:
	* Can be more intuitive and easier to read in certain contexts.
	* Might provide a sense of encapsulation and separation of concerns.
2. **Function**: Pros:
	* Is a general-purpose, reusable construct that can be used anywhere.
	* Can be faster due to the simplicity of function calls (no overhead from method invocation).
3. **Method**: Cons:
	* May incur additional overhead due to instance creation and method lookup.
	* Might be less flexible than functions in certain situations.

**Library:**

In this benchmark, no external libraries are used or required.

**Special JS Feature/Syntax:**

There is no special JavaScript feature or syntax being tested. The focus is on the performance difference between invoking methods and standalone functions.

**Other Considerations:**

When writing JavaScript code, consider the context in which your code will be executed:

* If you need to perform computations that depend on the state of an object, using a method might be more suitable.
* For simple computations that don't rely on object state, using a function can be faster and more efficient.

**Alternatives:**

Other alternatives for adding 1 to a value include:

1. **Arrow functions**: `const add = (value) => value + 1;`
2. **Anonymous functions**: `(function(value) { return value + 1; })(10);`
3. **Template literals**: `${10} + 1`
