Benchmark: Inline vs external

Script Preparation code:

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}

const PRIORITY_ORDER= [
  "SUCCESSFUL",
  "INPROGRESS",
  "FAILED",
];

function priority1(state) {
  return PRIORITY_ORDER.indexOf(state)
}

function priority2(state) {
  return [
  "SUCCESSFUL",
  "INPROGRESS",
  "FAILED",
].indexOf(state)
}

Tests:

external
const POSSIBILITIES = [ "SUCCESSFUL", "INPROGRESS", "FAILED", ]; const value = POSSIBILITIES[getRandomInt(3)]; priority1(value);
inlined
const POSSIBILITIES = [ "SUCCESSFUL", "INPROGRESS", "FAILED", ]; const value = POSSIBILITIES[getRandomInt(3)]; priority2(value);

Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net.

The provided JSON represents a benchmark test that compares two approaches: inlining and externalizing a function call. Here's a breakdown of what's being tested:

**Benchmark Definition**

The benchmark definition is a JSON object that contains metadata about the test, such as its name, description, and script preparation code. In this case, we have a single benchmark with two variations: "inline" and "external". The script preparation code defines two functions, `priority1` and `priority2`, which are used to determine the priority of a state value.

**Script Preparation Code**

The script preparation code includes a utility function `getRandomInt(max)` that generates a random integer between 0 and `max-1`. It also defines an array `PRIORITY_ORDER` containing three string values: "SUCCESSFUL", "INPROGRESS", and "FAILED". These values will be used to determine the priority of state.

**Html Preparation Code**

There is no HTML preparation code provided, which means that this benchmark does not require any HTML setup or rendering before running the tests.

**Individual Test Cases**

The individual test cases are represented as an array of objects, each containing a "Benchmark Definition" and a "Test Name". There are two test cases:

1. "external": This test case uses the `priority1` function to determine the priority of the state value.
2. "inlined": This test case uses the `priority2` function to determine the priority of the state value.

**Library**

The `priority1` and `priority2` functions rely on the JavaScript built-in `indexOf()` method, which returns the index of a specified element in an array. The purpose of this library is to provide a simple way to look up values in an array.

**Special JS Feature/Syntax**

There are no special JavaScript features or syntax used in this benchmark. The tests only rely on standard JavaScript functionality.

**Options Compared**

The two test cases compare the performance of calling `priority1` and `priority2` with external and inline references, respectively. Inlining means that the function call is embedded directly within the code, whereas externalizing means that the function call is made separately from the surrounding code.

**Pros and Cons**

Inlining:

* Pros:
	+ Can lead to better performance due to reduced overhead of function calls.
	+ Can improve cache locality by reducing the number of memory accesses.
* Cons:
	+ May make the code harder to read and maintain, especially for larger functions.
	+ Can increase the risk of errors due to shared state or side effects.

Externalizing:

* Pros:
	+ Makes the code easier to read and maintain, as each function call is separate from the surrounding code.
	+ Reduces the risk of errors due to shared state or side effects.
* Cons:
	+ May lead to slightly higher performance overhead due to function calls.
	+ Can reduce cache locality if the functions are not optimized for cache-friendly access patterns.

**Other Alternatives**

There are several other alternatives for benchmarking JavaScript performance, including:

1. V8 Benchmark Suite: A collection of benchmarks developed by Google's V8 JavaScript engine team.
2. jsPerf: A popular online platform for testing and comparing JavaScript performance.
3. Benchmark.js: A lightweight library for writing high-performance benchmarks in JavaScript.

These alternatives may offer different features, flexibility, or focus areas compared to MeasureThat.net, but they can provide valuable insights into JavaScript performance optimization techniques.
