Benchmark: jQuery css vs JS style vs fastCss (3)

HTML Preparation code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>
<div class="a" style="height: 100vh; width: 100vw; margin-top: 100px;"></div>

Script Preparation code:

jQuery.fn.fastCss = function(property, value)
{
    this.each(function(){
        this.style[property] = value;
    });
}

jQuery.fn.fastMultipleCss = function(obj)
{
    this.each(function(){
        for (const [key, value] of Object.entries(obj))
            this.style[key] = value;
    });
}

Tests:

jQuery css
const a = $(".a"); a.css("height", "100vh"); a.css("width", "100vw"); a.css("margin-top", "50px");
JS style
const a = $(".a"); a.each(function(){ this.style.height = "100vh"; this.style.width = "100vw"; this.style["margin-top"] = "50px"; });
jQuery fastCss
const a = $(".a"); a.fastCss("height", "100vh"); a.fastCss("width", "100vw"); a.fastCss("margin-top", "50px");
jQuery fastMultipleCss
const a = $(".a"); a.fastMultipleCss({height: "100vh", width: "100vw", "margin-top": "50px"});

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

**Benchmark Definition**

The provided JSON represents a benchmark that compares three approaches to set CSS styles for HTML elements:

1. **jQuery css**: Uses the `css()` method to set multiple styles at once.
2. **JS style**: Uses a loop with the `style` property to set each style individually.
3. **jQuery fastCss**: A custom implementation of `fastCss()` by jQuery, which is supposed to be faster than the standard `css()` method.

**Options Compared**

The benchmark compares these three options:

* **Pros and Cons:**
	+ **jQuery css**: Fast, but may not be as efficient as other methods.
	+ **JS style**: May be slower due to the loop and individual property accesses.
	+ **jQuery fastCss**: Supposed to be faster than `css()`, but its performance is being tested in this benchmark.
* **Other Considerations:**
	+ The benchmark also includes a fourth option, **jQuery fastMultipleCss**, which seems to be similar to `fastCss()` but takes an object with multiple style settings. Its purpose and performance are not explicitly stated.

**Libraries**

The benchmark uses jQuery as a library. Specifically:

* jQuery provides the `css()` method for setting styles.
* jQuery also provides the custom implementation of `fastCss()` which is being tested in this benchmark.

**Special JS Features or Syntax**

None mentioned, but it's worth noting that the use of `$(selector)` and `.each()` suggests that this benchmark is using the jQuery library and its internal iteration methods to set styles on elements.

**Alternatives**

Other approaches to setting CSS styles could include:

* Using `document.querySelector()` and then accessing the `style` property directly.
* Creating a custom function or class to manage style updates.
* Using other libraries or frameworks that provide similar functionality (e.g., React, Angular).

However, it's worth noting that the MeasureThat.net benchmark is focused on comparing the performance of specific options within jQuery, rather than exploring alternative approaches.

**Test Users**

This benchmark appears to be targeting developers who:

* Are already familiar with jQuery and its methods.
* May be interested in optimizing their CSS updates or understanding the trade-offs between different approach.
* Might be looking for a quick way to compare the performance of different options within jQuery.
