Benchmark: C vs F - MeasureThat.net

Script Preparation code:

function fnUsage(arg1, arg2, arg3) {
    return {
        arg1,
        arg2,
        arg3,
        getArgs() {
            return [arg1, arg2, arg3];
        },
    };
}
window.fnUsage = fnUsage;

class ClassUsage {
    constructor(arg1, arg2, arg3) {
        this.arg1 = arg1;
        this.arg2 = arg2;
        this.arg3 = arg3;
    }
    getArgs() {
        return [this.arg1, this.arg2, this.arg3];
    }
}

window.ClassUsage = ClassUsage;

Tests:

Let's dive into the explanation of what is tested on the provided JSON.

**Benchmark Definition**

The benchmark definition represents a JavaScript microbenchmark that compares two approaches: using a simple function (`fn`) and using a class (`ClassUsage`). The script preparation code defines these two entities:

1. `fnUsage`: a global function that returns an object with three properties (`arg1`, `arg2`, and `arg3`) and a `getArgs` method.
2. `ClassUsage`: a global class that takes three constructor arguments and has the same three properties as well, plus a `getArgs` method.

**Options Compared**

The benchmark compares two options:

A) Using a simple function (`fn`) to access the object's properties directly:
```javascript
const fn = fnUsage(1, 2, 3);
fn.arg1;
fn.arg2;
fn.arg3;
fn.getArgs();
```

B) Using an instance of the `ClassUsage` class to access its properties and methods:
```javascript
const cl = new ClassUsage(1, 2, 3);
cl.arg1;
cl.arg2;
cl.arg3;
cl.getArgs();
```

**Pros and Cons**

A) **Using a simple function**:

Pros:

* Easy to implement and understand.
* Direct access to object properties is often faster.

Cons:

* May not be compatible with all browsers or environments that support classes.
* Does not provide the same level of encapsulation as using an instance of a class.

B) **Using an instance of `ClassUsage`**:

Pros:

* Provides better encapsulation and control over object state.
* Can be more efficient in certain scenarios, especially when accessing properties through getter methods.

Cons:

* Requires creating an instance of the class, which can introduce overhead.
* May not be as straightforward to understand or implement.

Other considerations:

* The `getArgs` method is used in both approaches. This suggests that the benchmark is focused on measuring the performance difference between direct property access and accessing properties through getter methods.
* The use of global variables (`window.fnUsage` and `window.ClassUsage`) implies that the benchmark may be sensitive to external dependencies or side effects.

**Library and Special JS Features**

There are no libraries mentioned in the provided JSON. However, note that the `ClassUsage` class uses JavaScript classes, which were introduced in ECMAScript 2015 (ES6). This suggests that the benchmark is running on a modern browser or environment that supports ES6+ syntax.

**Alternatives**

If you wanted to create a similar benchmark using alternative approaches, you could consider:

* Using an object literal instead of a class
* Creating a function that returns an object with properties and methods
* Using a library like Lodash or Ramda to implement the `getArgs` method
* Optimizing one of the approaches (e.g., inlining the getter methods)
