Benchmark: Early out maybe?

Script Preparation code:

var a = function() {
    const apiresponse = {
        error: '', 
        isError: false,
        payload: undefined
    }
    try {
        // do stuff 
        if (Math.random() < 0.1) throw new Error("Panic!!!1")
        apiresponse.payload = 1;
    } catch (error) {
        apiresponse.error = error.message;
        apiresponse.isError = true;
    } 
    return apiresponse;
}

var b = function() {
    const apiresponse = {
        error: '', 
        isError: false,
        payload: undefined
    }
    try {
        // do stuff 
        if (Math.random() < 0.1) throw new Error("Panic!!!1")
        apiresponse.payload = 1;
        return apiresponse
    } catch (error) {
        apiresponse.error = error.message;
        apiresponse.isError = true;
        return apiresponse
    } 
}

Tests:

Let's dive into the world of microbenchmarks.

**Benchmark Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The benchmark in question tests two functions, `a()` and `b()`, which are similar but have some differences in their return statement handling.

**Script Preparation Code**

The script preparation code defines two functions, `a()` and `b()`. Both functions:

1. Create an object `apiresponse` with default values.
2. Try to execute some code (simulated by "do stuff").
3. Introduce randomness: there's a 10% chance of throwing an error (`Panic!!!1`) using `Math.random() < 0.1`.
4. If an error occurs, update the `apiresponse` object with the error message and set `isError` to true.
5. In function `b`, after updating `apiresponse.payload = 1;`, it also returns the updated `apiresponse`.

The key difference between the two functions is that in function `a`, the return statement is only present if an error occurs, whereas in function `b`, a return statement is always present.

**Html Preparation Code**

There is no HTML preparation code provided for this benchmark, which means that the benchmark focuses solely on the JavaScript code.

**Options Compared**

In the individual test cases, two options are compared:

1. **One Return**: This option calls function `a()` 10,000 times without any return statements.
2. **Two Return**: This option calls function `b()` 10,000 times with a return statement after updating `apiresponse.payload = 1;`.

**Pros and Cons**

* **One Return**: The main advantage is that it simulates a typical scenario where the function might not always need to return immediately.
* However, this approach may not be representative of real-world scenarios where functions often need to return values.

* **Two Return**: This approach might be more representative of real-world scenarios where functions frequently return values. However, it introduces an extra return statement, which could potentially impact performance due to the overhead of function calls.

**Library and Special JS Feature**

Neither function uses any external libraries or special JavaScript features beyond what's normally available in modern browsers.

**Other Considerations**

When creating microbenchmarks like this one, consider the following:

* Keep your benchmarks small and focused on a specific aspect of performance.
* Use realistic scenarios to ensure your benchmarks are representative of real-world usage.
* Avoid including unnecessary code or external libraries that might skew results.
* Test different options (like `one return` vs. `two return`) to see which approach performs better.

**Alternatives**

If you're looking for alternative benchmarking tools, consider the following:

* **Benchmark.js**: A lightweight JavaScript benchmarking library that allows you to write custom benchmarks and run them in various environments.
* **jsbench**: A web-based JavaScript benchmarking platform that provides a simple way to create and run benchmarks.

Keep in mind that each tool has its strengths and weaknesses, so it's essential to choose the one that best fits your needs.
