Benchmark: belongs-line - MeasureThat.net

Script Preparation code:

var x = 490;
var y = 334;
var from = { x: 320, y: 160 }
var to = { x: 640, y: 480 }

function belongsToRectangle(point, rectangle) {
  const from = { x: rectangle.x - 0.5*rectangle.width, y: rectangle.y - 0.5*rectangle.height };
  const to = { x: from.x + rectangle.width, y: from.y + rectangle.height };

  return (from.x <= point.x) && (point.x <= to.x) && (from.y <= point.y) && (point.y <= to.y);
}

function belongsToInfiniteLine(point, from, to) {
  const distance = (to.x - from.x)*(point.y - from.y) - (to.y - from.y)*(point.x - from.x);
  return Math.abs(distance) < 1000;
}

Tests:

belongsToRectangle
const rectangle = { x: 0.5*(from.x + to.x), y: 0.5*(from.y + to.y), width: Math.max(Math.abs(from.x - to.x), 10), height: Math.max(Math.abs(from.y - to.y), 10), }; belongsToRectangle({ x, y }, rectangle);
belongsToInfiniteLine
const rectangle = { x: 0.5*(from.x + to.x), y: 0.5*(from.y + to.y), width: Math.max(Math.abs(from.x - to.x), 10), height: Math.max(Math.abs(from.y - to.y), 10), }; belongsToInfiniteLine({ x, y }, from, to);
belongsToInfiniteLine_fixed
belongsToInfiniteLine({ x, y }, from, to);

Let's break down the provided benchmark definition and test cases.

**Benchmark Definition**

The benchmark is defined by a JSON object with the following properties:

* `Name`: The name of the benchmark, which is "belongs-line".
* `Description`: An empty string indicating that no description is available for this benchmark.
* `Script Preparation Code`: A code snippet that initializes variables and defines two functions:
	+ `belongsToRectangle(point, rectangle)`: This function checks if a given point lies within a rectangle defined by the `from` and `to` points. The rectangle is calculated as the 50% overlap between the lines defined by `from` and `to`.
	+ `belongsToInfiniteLine(point, from, to)`: This function checks if a given point lies on an infinite line segment defined by two points (`from` and `to`). The distance from the point to the line is calculated using the formula `(to.x - from.x)*(point.y - from.y) - (to.y - from.y)*(point.x - from.x)`.
* `Html Preparation Code`: An empty string indicating that no HTML preparation code is needed.

**Test Cases**

The benchmark consists of three test cases:

1. **belongsToRectangle**: This test case calls the `belongsToRectangle` function with a point and a rectangle defined by the previous script preparation code.
2. **belongsToInfiniteLine**: This test case calls the `belongsToInfiniteLine` function with a point, two points (`from` and `to`) defined in the script preparation code, and without any additional parameters.
3. **belongsToInfiniteLine_fixed**: This test case is identical to the previous one but does not call the `belongsToRectangle` function before it.

**Options Compared**

The three test cases compare different approaches:

* **belongsToRectangle**: Compares the performance of calling `belongsToRectangle` with a pre-defined rectangle.
* **belongsToInfiniteLine**: Compares the performance of calling `belongsToInfiniteLine` without any additional parameters (i.e., using only `from` and `to`) versus using all three parameters (`point`, `from`, and `to`).
* **belongsToInfiniteLine_fixed**: Is identical to the previous one, but does not call `belongsToRectangle` before it. This test case likely aims to measure the performance of the `belongsToInfiniteLine` function alone.

**Pros and Cons**

Here are some pros and cons for each approach:

* `belongsToRectangle`:
	+ Pros: Easy to understand and implement, uses a well-defined rectangle.
	+ Cons: May not accurately represent real-world scenarios where rectangles are not used.
* `belongsToInfiniteLine` (without additional parameters):
	+ Pros: More representative of real-world scenarios, where lines are often used.
	+ Cons: Requires more processing power to calculate the line segment.
* `belongsToInfiniteLine_fixed`:
	+ Pros: Allows for a direct comparison of the performance of `belongsToInfiniteLine` alone.
	+ Cons: Does not take into account any potential overhead of calling `belongsToRectangle` before it.

**Library and Special JS Features**

The benchmark uses the following library:

* None explicitly mentioned, but the use of the `Math.max` function suggests that the benchmark is using modern JavaScript features (specifically, ECMAScript 2015 or later).

No special JS features are mentioned in this explanation. If you'd like to know more about specific features, feel free to ask!

**Other Alternatives**

If the benchmark were to be modified or expanded, some alternative approaches could be considered:

* Using different types of geometric shapes (e.g., triangles, circles).
* Incorporating more complex scenarios, such as intersecting lines or polygons.
* Adding additional parameters to `belongsToInfiniteLine`, such as a line segment's slope or endpoint coordinates.
* Using different browsers or platforms to simulate diverse user experiences.

Keep in mind that these alternatives would require significant changes to the benchmark definition and test cases.
