Benchmark: TestBufferRun - MeasureThat.net

Script Preparation code:

function TestSub(b1, b2, b3){
  var i=0;
  if(b1 && b2 && b3){
    i+=1;
  }
}

Tests:

Test1
var Buff1 = new Blob(['<a id="a">Test</a>'], {type: "text/html"}); var Buff2 = new Blob(['<a id="a">Test</a>'], {type: "text/html"}); var Buff3 = new Blob(['<a id="a">Test</a>'], {type: "text/html"}); TestSub(Buff1, Buff2, Buff3);
Test2
TestSub(new Blob(['<a id="a">Test</a>'], {type: "text/html"}), new Blob(['<a id="a">Test</a>'], {type: "text/html"}), new Blob(['<a id="a">Test</a>'], {type: "text/html"}));

Let's break down what's being tested in this JavaScript microbenchmark.

**Benchmark Definition**

The provided `json` represents the benchmark definition for "TestBufferRun". The script preparation code defines a function called `TestSub`, which takes three arguments: `b1`, `b2`, and `b3`. The function checks if all three arguments are truthy, and if so, increments a variable `i` by 1.

The purpose of this benchmark is to compare the performance of calling `TestSub` with different numbers of arguments passed to it. Specifically, there are two test cases:

* Test Case 1: Calls `TestSub` with three separate Blob objects (`Buff1`, `Buff2`, and `Buff3`) created using the `Blob` constructor.
* Test Case 2: Calls `TestSub` with three separate Blob objects as individual arguments.

**Library: Blob**

The `Blob` constructor is a JavaScript library that allows you to create binary blobs from strings. In this benchmark, it's used to create three identical HTML documents (`<a id="a">Test</a>`) and assign them to separate variables (`Buff1`, `Buff2`, and `Buff3`).

The purpose of using `Blob` here is likely to demonstrate the performance impact of calling a function with different numbers of arguments, as the Blob creation process is likely to be similar in both test cases.

**Special JavaScript Features/Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark. The code uses standard JavaScript syntax and features, such as functions, variables, and conditional statements.

**Pros and Cons of Different Approaches**

In this benchmark, the different approaches being compared are:

* Calling `TestSub` with three separate arguments (`Buff1`, `Buff2`, and `Buff3`)
* Calling `TestSub` with three separate Blob objects created using the `Blob` constructor

The pros and cons of these approaches are likely to be similar in terms of performance, as both test cases involve creating identical HTML documents. However, calling `TestSub` with a single argument (a Blob object) might be slightly more efficient, as it eliminates the need for multiple function calls.

**Other Alternatives**

To create identical Blob objects, other alternatives could include:

* Using an array of strings to create the Blob data
* Using a string literal and parsing it into a Blob object using `Blob.fromArray()`
* Using a library like `jsdom` to parse the HTML document and extract its contents as a Blob object

However, in this specific benchmark, the `Blob` constructor is used to create identical Blob objects, so these alternatives are not relevant.

**Device Platform and Operating System**

The benchmark results show that both test cases were executed on Chrome 64 running on Windows. The device platform is listed as "Other", but it's likely that the actual device being tested was a Windows-based desktop computer.

**Executions Per Second**

The benchmark results show that Test Case 2 (calling `TestSub` with three separate arguments) had an average of 2146 executions per second, while Test Case 1 (calling `TestSub` with three separate Blob objects) had an average of 2177.51492 executions per second. This suggests that calling `TestSub` with a single argument (a Blob object) might be slightly faster than calling it with multiple arguments.
