Benchmark: getter vs method v2

Tests:

get
class User { constructor(name, age) { this.name = name; this.age = age; } get isAdult() { return 20 <= this.age } } const user = new User('foo', 20); const isAdult = user.isAdult
method
class User { constructor(name, age) { this.name = name; this.age = age; } isAdult() { return 20 <= this.age } } const user = new User('foo', 20); const isAdult = user.isAdult()

Let's break down the provided benchmark definition and test cases to understand what is being tested.

**Benchmark Definition**

The benchmark definition represents two different ways of accessing a method in JavaScript: using getter syntax (`"get"`) versus using function notation (`"method"`). The script preparation code and HTML preparation code are empty, indicating that no additional setup or rendering is required for the benchmark.

**Individual Test Cases**

There are two test cases:

1. **"get"**: This test case uses the getter syntax to access the `isAdult` method.
```javascript
class User {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }
  get isAdult() {
    return 20 <= this.age;
  }
}

const user = new User('foo', 20);
const isAdult = user.isAdult;
```
In this case, the getter syntax (`"get"`) is used to access the `isAdult` method.

2. **"method"**: This test case uses function notation to access the `isAdult` method.
```javascript
class User {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }
  isAdult() {
    return 20 <= this.age;
  }
}

const user = new User('foo', 20);
const isAdult = user.isAdult();
```
In this case, the function notation (`"method"`) is used to access the `isAdult` method.

**Options Compared**

The benchmark compares two options:

1. **Getter Syntax ("get")**: This approach uses the getter syntax to access the `isAdult` method.
2. **Function Notation ("method")**: This approach uses function notation to access the `isAdult` method.

**Pros and Cons of Each Approach**

Here are some pros and cons of each approach:

* **Getter Syntax ("get")**:
	+ Pros: Can be more readable and concise, as it allows for a single-expression accessor.
	+ Cons: May not be supported by older browsers or environments that do not understand getters.
* **Function Notation ("method")**:
	+ Pros: More widely supported across different browsers and environments, as it is similar to traditional function calls.
	+ Cons: Requires more code and may be less readable due to the need for parentheses.

**Library Usage**

In this benchmark, no libraries are explicitly mentioned. However, some JavaScript features (such as getters) rely on built-in or standard library functions.

**Special JS Features/Syntax**

There is no special JavaScript feature or syntax being tested in this benchmark. The focus is solely on comparing two different approaches to accessing a method: getter syntax and function notation.

**Alternatives**

If you were to rewrite this benchmark, you might consider adding alternative test cases that explore other aspects of method invocation, such as:

* Using arrow functions
* Using `call` or `apply` methods to invoke the method
* Comparing performance with different types of objects (e.g., native arrays vs. custom array-like objects)

However, these alternatives are not present in this specific benchmark.

Keep in mind that benchmarking JavaScript performance can be complex and nuanced, as it depends on various factors such as the specific implementation details, browser support, and system configuration.
