Benchmark: canvas fillStyle color format w/ rendering 2

Script Preparation code:

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

Tests:

hex rgba
ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.clearRect(0, 0, 1920, 1080); ctx.fillStyle = "#FF000066"; 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, 0.4)"; 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(255,0,0,0.4)"; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.fillRect(0, 0, 1920, 1080);

Let's dive into the world of JavaScript microbenchmarks.

**Overview**

MeasureThat.net is a platform that allows users to create and run JavaScript microbenchmarks, providing insights into the performance differences between various approaches, libraries, and features.

The provided benchmark definition json represents a simple test case for comparing different color formats in the Canvas API. The individual test cases are designed to measure the performance of various rgba color format implementations.

**Options being compared**

In this benchmark, the following options are being compared:

1. **Hex RGBA**: This option uses the hex representation of colors (e.g., `#FF000066`).
2. **RGBA function with spaces**: This option uses a custom function to parse rgba values with spaces (e.g., `rgba(255, 0, 0, 0.4)`).
3. **RGBA function without spaces**: This option uses the same custom function as above, but without spaces.

**Pros and Cons**

Here are some pros and cons of each approach:

1. **Hex RGBA**:
	* Pros: Simple to read and write, widely supported.
	* Cons: Can lead to errors if not properly sanitized.
2. **RGBA function with spaces**: This option uses a custom function to parse rgba values, which can introduce overhead due to the extra parsing step.
3. **RGBA function without spaces**:
	* Pros: Faster execution speed since there's no additional parsing overhead.
	* Cons: May be less readable and more prone to errors if not implemented correctly.

**Library**

In this benchmark, the Canvas API is used, which is a popular library for rendering 2D graphics in web browsers. The `getContext("2d")` method creates a 2D drawing context, allowing you to perform operations like filling shapes with specific colors.

**Special JS feature or syntax**

None of the individual test cases use any special JavaScript features or syntax beyond what's required by the Canvas API. They rely on standard JavaScript and DOM APIs.

**Alternatives**

If you're interested in exploring alternative approaches for similar benchmarks, here are a few options:

1. **CSS Color**: Instead of using rgba colors, you could compare performance with CSS color values (e.g., `rgba(255, 0, 0, 0.4)`).
2. **WebGL**: If you're targeting WebGL-enabled browsers, you could compare the performance of different rgba implementations within a WebGL context.
3. **Other libraries**: Depending on your specific use case, you might consider using other libraries like React or Angular, which provide their own set of APIs for handling colors and rendering graphics.

Keep in mind that each alternative would require significant changes to the benchmark definition and implementation.
