Benchmark: Lodash sortby vs array spread sort

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

Let's dive into the world of JavaScript microbenchmarks.

The provided JSON represents a benchmark test case created using MeasureThat.net, which compares the performance of two approaches: Lodash's `sortBy` function and the native `sort()` method on an array.

**Tested Options**

Two options are being compared:

1. **Lodash's `sortBy` function**: This function takes an array and a sorting key as input and returns a new sorted array.
2. **Native `sort()` method on an array**: This is a built-in JavaScript method that sorts the elements of an array in place, returning the sorted array.

**Pros and Cons**

Both approaches have their advantages and disadvantages:

* **Lodash's `sortBy` function**:
	+ Pros:
		- More concise and readable code
		- Handles complex sorting scenarios with ease (e.g., sorting objects by multiple keys)
		- Less error-prone, as it handles edge cases automatically
	+ Cons:
		- Adds external dependency (Lodash library), which may increase page load times or require additional setup
		- May introduce overhead due to the need for function calls and object creation
* **Native `sort()` method on an array**:
	+ Pros:
		- No external dependencies, making it a self-contained solution
		- Generally faster and more efficient, as it's implemented in native code
		- Works well with smaller datasets or simple sorting scenarios
	+ Cons:
		- Less readable and concise code compared to `sortBy`
		- Requires manual handling of edge cases (e.g., null or undefined values)

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides a wide range of functions for tasks like array manipulation, object transformation, and more. The `sortBy` function is one of its many useful tools for sorting arrays.

**Special JS Feature/Syntax: None mentioned**

There are no special JavaScript features or syntax used in this benchmark test case. Both approaches rely on standard JavaScript programming concepts.

**Other Alternatives**

If you need to sort an array, other alternatives to the `sort()` method include:

* Using the `Array.prototype.sort()` method directly
* Utilizing a different sorting library (e.g., underscore.js or ramda)
* Implementing a custom sorting algorithm (e.g., quicksort, mergesort, or heapsort)

Keep in mind that each alternative has its own trade-offs and performance characteristics. The choice ultimately depends on the specific requirements of your project and personal preference.

Now that we've explored this benchmark test case, you should have a better understanding of how Lodash's `sortBy` function compares to the native `sort()` method on an array in terms of performance.
