Benchmark: Ramda unique 4 - MeasureThat.net

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.27.0/ramda.min.js"></script>

Script Preparation code:

var data = _.range(8000).map(function(i) {
  return {
    counter: i,
    date: new Date(),
    name: 'Adam',
    value: (i % 2500) * 0.0001 + 10000
  }
});
var compareNumberDecimal1 = (a, b, decimal_place) => a.toFixed(decimal_place) === b.toFixed(decimal_place);
var compareNumberDecimal2 = (a, b, decimal_place) => Math.round(a * (10 ** decimal_place)) === Math.round(b * (10 ** decimal_place));

Tests:

Equal toFixed
R.uniqWith( (a, b) => compareNumberDecimal1(a.value, b.value, 4), data )
Equal round
R.uniqWith( (a, b) => compareNumberDecimal2(a.value, b.value, 4), data )

I'd be happy to explain the provided benchmark and its various aspects.

**Benchmark Definition:**

The benchmark definition is a JSON object that represents a JavaScript microbenchmark. It consists of two parts:

1. **Script Preparation Code:** This section provides the initial code required to prepare the data for the benchmark. In this case, it creates an array of 8,000 objects using Ramda's `_.range` function and maps each object to have some properties. The script also defines two functions: `compareNumberDecimal1` and `compareNumberDecimal2`, which will be used to compare numbers with a specific decimal place.
2. **Html Preparation Code:** This section provides the HTML code required to include the Ramda library in the benchmark.

**Individual Test Cases:**

The benchmark definition includes two test cases:

1. **Equal toFixed:** This test case uses the `compareNumberDecimal1` function to compare numbers with a fixed decimal place of 4.
2. **Equal round:** This test case uses the `compareNumberDecimal2` function, which rounds numbers to a specific decimal place before comparison.

**Library: Ramda**

Ramda is a functional programming library for JavaScript that provides a set of higher-order functions and utilities for working with data. In this benchmark, Ramda's `R.uniqWith` function is used to remove duplicates from the array of objects while preserving the uniqueness of the values.

The purpose of using Ramda in this benchmark is to provide a standardized way of comparing numbers with different decimal places, ensuring consistency across different browsers and environments.

**Special JS Feature/Syntax:**

There are no special JavaScript features or syntaxes used in this benchmark. The code relies on standard JavaScript concepts, such as functions, arrays, and object properties.

**Other Considerations:**

When running benchmarks like this one, several factors come into play:

* **Browser differences:** Different browsers may have varying implementations of the same API functions, leading to variations in performance.
* **Platform and device differences:** The benchmark is run on a desktop platform with Mac OS X 10.14.5, which may not be representative of all platforms (e.g., mobile devices).
* **Memory allocation and garbage collection:** The benchmark's performance can be affected by the memory allocation and garbage collection mechanisms used by the browser.
* **Cache effects:** The benchmark results might be influenced by cache effects, where the data is cached in the browser or operating system.

**Alternatives:**

If you're interested in running benchmarks on different browsers or platforms, there are alternatives to MeasureThat.net:

* **Benchmark.js:** A lightweight, modular benchmarking framework for JavaScript.
* **WebPageTest:** A performance testing tool that measures the speed and efficiency of websites across various browsers and devices.
* **Benchpress:** A high-performance benchmarking library for JavaScript and Node.js.

These tools can help you create more comprehensive benchmarks and compare performance across different environments.
