Benchmark: canvas fillStyle color format w/ rendering

Script Preparation code:

var canvas = document.createElement("canvas");
canvas.width = 1920;
canvas.height = 1080;
var ctx = canvas.getContext("2d");

Tests:

hex rgb
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "#FF0000"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);
hex rgba
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "#FF0000FF"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);
rgb func with spaces
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "rgb(255, 0, 0)"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);
rgb func without spaces
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "rgb(255,0,0,1)"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);
rgba func with spaces
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "rgba(255, 0, 0, 1)"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);
rgba func without spaces
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "rgba(255,0,0,1)"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);

Let's dive into the world of JavaScript microbenchmarks.

**Benchmark Overview**

The provided JSON represents a benchmarking test for measuring the performance of different color formats in Canvas rendering. Specifically, it tests the execution speed of `fillStyle` with various color formats: hex (hexadecimal), rgb, and rgba.

**Options Compared**

There are four options being compared:

1. **Hex RGBA**: Color format using hexadecimal notation with alpha channel (e.g., `#FF0000FF`)
2. **Hex RGB**: Color format using hexadecimal notation without alpha channel (e.g., `#FF0000`)
3. **RGB Function**: Color format using a function that takes three arguments (red, green, and blue) to create the color
4. **RGBA Function with Spaces**: Color format using a function that takes four arguments (red, green, blue, and alpha) with spaces in between (e.g., `rgb(255, 0, 0, 1)`)

**Pros and Cons**

Here's a brief summary of the pros and cons for each option:

* **Hex RGBA**: Fast execution, as it only involves simple string manipulation. However, it may not be as readable or maintainable as other formats.
* **Hex RGB**: Similar to hex RGBA, but without alpha channel. This format is also fast and easy to read.
* **RGB Function**: Requires more computations than the above formats, as it needs to parse and execute a function. However, this format can be more flexible and readable, especially for complex color calculations.
* **RGBA Function with Spaces**: Combines the best of both worlds: readability and performance. The spaces in the function call make it easier to read, while still allowing for fast execution.

**Library and Syntax**

The `Canvas` API is used extensively in this benchmarking test. Specifically, the `ctx.fillStyle` property is used to set the fill color, which is then applied using `ctx.fillRect`. No libraries are required for this benchmark.

**Special JS Feature or Syntax**

No special JavaScript features or syntaxes are employed in this benchmark. The tests only focus on comparing different color formats and their execution speeds.

Now that we've taken a deep breath, let's move forward with understanding the results of this benchmarking test.
