Benchmark: lodash remove vs native splice vs shift& pop

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>

Script Preparation code:

var max = 10000000; // 10,000,000 (10 Million)

var arr = [];
for (var i = 0; i <= max; i++) {
    arr.push(i);
}

Array.prototype.myShiftDelete = function arrayMyShiftDelete(index) {
    var stop = this.length - 1;
    while (index < stop) {
        this[index] = this[++index];
    }

    this.pop();
}

Tests:

lodash
_.remove(arr, item => item === 890047);
native
const index = arr.findIndex(item => item === 890047); arr.splice(index, 1);
shift&pop
arr.myShiftDelete(890047);

Let's dive into the world of JavaScript microbenchmarks!

**Benchmark Overview**

MeasureThat.net is a platform where users can create and run JavaScript microbenchmarks to compare different approaches to solving specific problems. The provided benchmark definition involves removing an item from an array using three different methods: Lodash's `remove` function, native JavaScript's `splice` method, and a custom implementation using `shift&pop`.

**Options Compared**

The three options being compared are:

1. **Lodash's `remove` function**: A popular utility library that provides various functions for manipulating arrays and objects.
2. **Native JavaScript's `splice` method**: The built-in method used to remove or replace elements in an array.
3. **Custom implementation using `shift&pop`**: A simple implementation that uses the `shift` and `pop` methods to remove the specified item from the array.

**Pros and Cons of Each Approach**

1. **Lodash's `remove` function**:
	* Pros: Efficient, concise, and well-maintained code.
	* Cons: Adds additional library dependencies, may have performance overhead due to lazy evaluation.
2. **Native JavaScript's `splice` method**:
	* Pros: Fast, efficient, and widely supported.
	* Cons: Can be slower for small arrays or shallow modifications, may cause unnecessary reassignments of elements.
3. **Custom implementation using `shift&pop`**:
	* Pros: Simple, lightweight, and easy to understand.
	* Cons: May have performance overhead due to repeated shifts and pops, can be fragile if not implemented correctly.

**Library Descriptions**

In this benchmark, Lodash is used for its `remove` function. Lodash is a popular JavaScript utility library that provides various functions for manipulating arrays, objects, strings, numbers, and more. Its `remove` function takes an array and a predicate (a callback function) as arguments and returns the filtered array.

**Special JS Feature or Syntax**

None are mentioned in this benchmark definition.

**Other Considerations**

When choosing between these approaches, consider the following factors:

* Performance: If speed is critical, native JavaScript's `splice` method might be a better choice. However, for small arrays or shallow modifications, Lodash's `remove` function might be more efficient.
* Code readability and maintainability: The custom implementation using `shift&pop` is simple and easy to understand, while Lodash's `remove` function provides a concise but may require additional library dependencies.
* Robustness: Ensure that the custom implementation handles edge cases and errors correctly.

**Alternatives**

Other alternatives to consider when removing items from an array include:

* Using `filter` method instead of `splice`
* Implementing a custom sorting algorithm after removing elements
* Using `array.prototype.map()` and `slice()` methods for more complex data processing

Keep in mind that the choice of approach depends on the specific requirements and constraints of your project.
