Benchmark: Lodash sort vs ES5 sort when same functions are added

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

function getRandomInt(max) {
    return Math.floor(Math.random() * Math.floor(max));
}

var arr = [];
for (var i = 0; i < 100000; i++) {
    arr.push({
        value: getRandomInt(100)
    });
}

Tests:

_.sortBy
_.sortBy(arr, (a) => a.value);
array.prototype.sort
[...arr].sort((a,b) => a.value - b.value);

Let's dive into the provided JSON benchmark data.

**Overview of the Benchmark**

The test is comparing two sorting algorithms: Lodash's `sortBy` function and the built-in `sort` method on JavaScript arrays (ES5). The tests are run on Firefox 109, a desktop browser running Windows.

**Options Compared**

The two options being compared are:

1. **Lodash's `sortBy` function**: A utility function that sorts an array of objects based on a specified key. In this case, the key is the `value` property.
2. **Built-in `sort` method (ES5)**: A standard method for sorting arrays in JavaScript.

**Pros and Cons**

### Lodash's `sortBy` Function

Pros:

* **Convenience**: Lodash provides a convenient way to sort arrays of objects by a specified key, without having to write custom implementation.
* **Performance**: In this benchmark, Lodash's `sortBy` function appears to be faster than the built-in `sort` method.

Cons:

* **Dependency on Lodash library**: The test requires an instance of the Lodash library to be included in the HTML file. This may not be desirable for all testing environments.
* **Overhead**: Using a third-party library like Lodash can introduce additional overhead due to loading times and potential conflicts with other libraries.

### Built-in `sort` Method (ES5)

Pros:

* **Native performance**: The built-in `sort` method is likely to have native performance, as it's implemented in the browser's JavaScript engine.
* **No dependencies**: No external library needs to be included, making it a more straightforward choice for testing.

Cons:

* **Implementation complexity**: Writing a custom sorting algorithm can be complex and error-prone, especially when dealing with edge cases or large datasets.
* **Performance variability**: The performance of the built-in `sort` method may vary depending on the browser's implementation, which could affect benchmark results.

**Library Used: Lodash**

Lodash is a popular JavaScript utility library that provides a wide range of functions for tasks such as string manipulation, array manipulation, and more. In this case, the `sortBy` function is used to sort arrays of objects based on a specified key.

**Special JS Feature/Syntax**

None mentioned in the provided JSON data. However, it's worth noting that some modern JavaScript features like async/await or template literals might not be supported in older browsers, which could affect benchmark results.

**Other Alternatives**

For sorting algorithms, there are other alternatives to Lodash's `sortBy` function and the built-in `sort` method, such as:

* **Stable sorting algorithms**: Like Merge Sort, Quick Sort, or Heap Sort, which have a time complexity of O(n log n) but can be more complex to implement.
* **Custom implementation**: Writing a custom sorting algorithm from scratch, which can provide better control over performance and optimization.
* **Other libraries**: Such as jQuery's `sort` method or other specialized libraries like Ramda.

For testing JavaScript benchmarks, there are also other alternatives to MeasureThat.net, such as:

* **Jasmine**: A popular JavaScript testing framework for unit tests and integration tests.
* **Mocha**: Another widely used JavaScript testing framework that supports asynchronous tests and more.
* **Benchmark.js**: A lightweight benchmarking library that provides a simple way to create and run benchmarks.
