Benchmark: pick vs is - MeasureThat.net

HTML Preparation code:

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

Script Preparation code:

var obj = {
	visible: '1',
  	value: '2'
}

Tests:

pick
let i = ''; const set = (obj) => { Object.keys(obj).forEach(key => { i += obj[key]; }); } set(_.pick(obj, ['visible']));
if
let i = ''; const set = (obj) => { Object.keys(obj).forEach(key => { if (!obj[key]) { return; } i += obj[key]; }); } set({ visible: obj.visible });
if with variable
let i = ''; const set = (obj) => { Object.keys(obj).forEach(key => { const value = obj[key]; if (!value) { return; } i += value; }); } set({ visible: obj.visible });

Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net.

**Benchmark Definition**

The provided JSON defines a benchmark with three test cases:

1. **"pick vs is"`**: This benchmark compares two approaches to check if an object has a specific key: `lodash.pick()` and `if`/`else` statements.
2. **Individual test cases**: Three separate test cases are defined, each measuring the performance of one approach:
	* `"pick"`
	* `"if"`
	* `"if with variable"`

**Options Compared**

The two options being compared in the first benchmark are:

1. **`lodash.pick()`**: A function from the Lodash library that returns a new object containing only the specified properties from the original object.
2. **`if`/`else` statements**: A common approach to check if an object has a specific key, using conditional statements.

**Pros and Cons of Each Approach**

1. **`lodash.pick()`**:
	* Pros: concise, readable code; leverages optimized library function
	* Cons: requires including additional library (Lodash); might have overhead due to library dependencies
2. **`if`/`else` statements**:
	* Pros: no external library dependency; straightforward and easy to understand
	* Cons: can be verbose and repetitive; may lead to slower performance due to conditional checks

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides various functions for working with data structures, arrays, objects, and more. The `lodash.pick()` function is one of its many useful tools.

In the context of this benchmark, using `lodash.pick()` simplifies the code and allows for a concise comparison between the two approaches.

**Special JS Features/Syntax**

There are no special JavaScript features or syntaxes being tested in this benchmark. However, it's worth noting that some modern JavaScript features like arrow functions (`=>`), template literals (`\r\n\t${value}`), and ES6 classes (`const set = () => { ... }`) are not used in the provided code.

**Alternatives**

For those interested in exploring alternative approaches or libraries, here are a few options:

1. **`Object.keys()` and `for...of` loop**: Another way to iterate over object keys without using Lodash.
2. **`Object.hasOwn()`**: A built-in method for checking if an object has a specific property.
3. **Other JavaScript libraries**: There are many other libraries available that provide similar functionality to Lodash, such as `underscore.js`, `ramda.js`, or `js-obj`.

Keep in mind that the choice of approach and library ultimately depends on your project's requirements, performance constraints, and personal preference.

I hope this explanation helps you understand the context and nuances of the MeasureThat.net benchmark!
