Benchmark: delete vs this.$delete

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/vue@2"></script>
<div id="app" />

Script Preparation code:

const N = 1000;
const OBJ = [...Array(N).keys()].reduce((result, i) => ({
    ...result,
    [i]: i
}), {});

Tests:

delete
new Vue({ "el": "#app", data() { return { "obj": {...OBJ} }; }, mounted() { Object.keys(this.obj).forEach((i) => delete this.obj[i]); } });
this.$delete
new Vue({ "el": "#app", data() { return { "obj": {...OBJ} }; }, mounted() { Object.keys(this.obj).forEach((i) => this.$delete(this.obj, i)); } });

Let's break down the benchmark definition and test cases to understand what is being tested.

**Benchmark Definition**

The benchmark defines two JavaScript microbenchmarks: `delete` and `this.$delete`. The purpose of these benchmarks is to compare the performance of deleting properties from an object using the built-in `delete` operator versus using the `$delete` method provided by the Vue.js library.

**Options being compared**

There are two options being compared:

1. **Built-in `delete` operator**: This is the native JavaScript way of deleting a property from an object.
2. **Vue.js `$delete` method**: This is a method provided by the Vue.js library that deletes a property from an object.

**Pros and Cons of each approach**

**Built-in `delete` operator:**

Pros:

* Widely supported across different browsers and JavaScript engines
* Lightweight and efficient

Cons:

* Can be slower than the `$delete` method in certain scenarios (see below)
* May not work as expected in certain situations, such as when used with `Object.freeze()` or `Object Sealed()` methods

**Vue.js `$delete` method:**

Pros:

* Optimized for performance and can be faster than the built-in `delete` operator
* Provides additional functionality, such as deletion of multiple properties at once

Cons:

* Only supported by Vue.js library, which may limit its use in other projects
* Can add unnecessary overhead due to the library's presence

**Library: Vue.js**

The `$delete` method is part of the Vue.js library, which provides a set of reusable functions for building user interfaces. In this benchmark, the `Vue.js` library is used to create a new instance of the Vue.js framework and render an HTML element.

**Special JavaScript feature or syntax**

There is no special JavaScript feature or syntax being tested in this benchmark. Both options are standard JavaScript operations that are widely supported across different browsers and environments.

**Other alternatives**

If you wanted to test alternative methods for deleting properties from an object, some other approaches could be:

* Using `Object.prototype.hasOwnProperty.call()` to check if a property exists before deleting it
* Using `delete` with a function as its argument (e.g., `delete obj[f]`)
* Using a library like Lodash or Underscore.js that provides utility functions for working with objects

However, these alternatives are not being tested in this specific benchmark.
