Benchmark: Lodash sortBy vs orderBy

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:

orderBy
_.orderBy(arr,"value");
sortBy
_.sortBy(arr,"value");

Let's break down the benchmark and explain what is being tested.

**Benchmark Overview**

The benchmark compares two methods: `_.orderBy` and `_.sortBy`, which are part of the Lodash library. Both methods sort an array of objects based on a specific property ("value" in this case). The benchmark aims to determine which method is faster for this specific use case.

**Options Compared**

The two options being compared are:

1. `_._orderBy(arr, "value")`: This method sorts the array in ascending order using the `value` property as the sorting key.
2. `_._sortBy(arr, "value")`: This method also sorts the array based on the `value` property, but it sorts in descending order.

**Pros and Cons of Each Approach**

1. **_orderBy(arr, "value")**: This approach is suitable when you want to sort the array in ascending order.
	* Pros: Easy to understand and implement, as it directly uses the built-in `sort()` method with a custom sorting function.
	* Cons: May not be suitable for large datasets or complex data structures, as it relies on the JavaScript engine's sorting algorithm, which can be slow for very large datasets.
2. **_sortBy(arr, "value")**: This approach is suitable when you want to sort the array in descending order.
	* Pros: Can be useful when you need to prioritize elements based on their value in a specific order (e.g., showing more important elements first).
	* Cons: May not be as straightforward to implement or understand, as it requires using a custom sorting function with a negative key.

**Lodash Library and its Purpose**

The Lodash library is a popular utility library for JavaScript that provides a wide range of functions for various tasks, such as array manipulation, string manipulation, and more. In this benchmark, Lodash's `_.orderBy` and `_._sortBy` functions are used to simplify the sorting process.

**Special JS Feature or Syntax**

There doesn't appear to be any special JavaScript features or syntax being used in this benchmark.

**Other Alternatives**

If you don't want to use the Lodash library for sorting arrays, you can also use native JavaScript methods:

1. `arr.sort((a, b) => a.value - b.value)` for ascending order
2. `arr.sort((a, b) => b.value - a.value)` for descending order

Alternatively, you can use other libraries like `moment.js` or `date-fns` if your sorting logic involves dates or timestamps.

**Benchmark Preparation Code Explanation**

The script preparation code generates an array of 100,000 objects with random integers between 0 and 100. This is a common pattern for benchmarking array operations, as it allows you to test the performance of different sorting algorithms on large datasets.

**Benchmark Individual Test Cases**

Each individual test case defines a single benchmark using one of the `_.orderBy` or `._sortBy` functions. The test name reflects which specific function is being tested (e.g., "orderBy" and "sortBy").
