Benchmark: Multipromise resulter

Script Preparation code:

function delay(ms, val = true) {
  let timeoutId;
  return new Promise(resolve => {
    timeoutId = setTimeout(() => resolve(val), ms);
  });
}

function runTest(resultFunc) {
	const res = resultFunc();
	for(let i=0; i<20; i++) {
    	res.add(delay(i));
    }
  	return res.get();
}

Tests:

Function based
const createResultPromiseFunc = () => { let res = Promise.resolve(); return { get() { return res; }, add(nextPromise) { res = res.then(() => nextPromise); return this; } }; }; runTest(createResultPromiseFunc);
Array based
const createResultPromiseArray = () => { const res = []; return { get() { return Promise.all(res); }, add(nextPromise) { res.push(nextPromise); return this; } }; }; runTest(createResultPromiseArray);

I'll break down the provided benchmarking data and explain what's being tested, compared, and some pros and cons of each approach.

**Benchmark Definition JSON**

The benchmark definition represents two different ways to implement a "Multipromise Resulter" in JavaScript:

1. **Function-based implementation**: The first benchmark definition uses a function `createResultPromiseFunc` that returns an object with two methods: `get()` and `add(nextPromise)`. The `get()` method returns the resolved promise, while the `add(nextPromise)` method adds the next promise to the chain.
2. **Array-based implementation**: The second benchmark definition uses a function `createResultPromiseArray` that returns an object with two methods: `get()` and `add(nextPromise)`. However, instead of using a promise, it returns an array that is populated with promises through the `add()` method. The `get()` method then resolves to the all-promise resolved in the array.

**Options Compared**

The benchmark compares the performance of these two different approaches:

1. **Function-based implementation**: This approach uses a promise chain to handle asynchronous operations.
2. **Array-based implementation**: This approach uses an array to store promises and chains them together using the `add()` method.

**Pros and Cons of Each Approach**

**Function-Based Implementation:**

Pros:

* Easier to understand and implement for developers familiar with promise chaining.
* Less memory-intensive, as only one promise object is created.

Cons:

* May have slower performance due to the overhead of creating and managing a promise chain.

**Array-Based Implementation:**

Pros:

* Can be more efficient in terms of memory usage, as it uses an array instead of a promise chain.
* Allows for easier handling of asynchronous operations with multiple promises using array methods like `push()`.

Cons:

* More complex to understand and implement, especially for developers without experience with arrays and promise chains.
* May have slower performance due to the overhead of creating and managing the array and its promises.

**Library Used (if applicable)**

In both benchmark definitions, no external libraries are used. The implementations rely solely on JavaScript's built-in features, such as `Promise` objects and array methods.

**Special JS Features or Syntax**

No special JavaScript features or syntax are used in these benchmark definitions. They rely only on standard JavaScript constructs.

**Other Alternatives**

Other alternatives to implement a "Multipromise Resulter" could include:

* Using a task queue like `async/await` with `Promise.all()` or `Promise.race()`
* Implementing a custom data structure, such as a linked list or a stack, to handle asynchronous operations
* Utilizing a third-party library that provides similar functionality

Keep in mind that each of these alternatives would have their own pros and cons, and the choice ultimately depends on the specific requirements and constraints of the project.
