Benchmark: Array static - MeasureThat.net

Script Preparation code:

var self = {};

self.removeProperty = function (property) {
            var blacklist = ['type', 'identifier', 'isDisposable', 'disposeProperties', 'undisposeProperties', 'removeProperty', 'disposeObject', 'validateStatus'];

            if (blacklist.indexOf(property) === -1) {
                self[property] = null;
            }
        };

var blacklistSELF = ['type', 'identifier', 'isDisposable', 'disposeProperties', 'undisposeProperties', 'removeProperty', 'disposeObject', 'validateStatus'];
self.removeProperty2 = function (property) {
            
            if (blacklistSELF.indexOf(property) === -1) {
                self[property] = null;
            }
        };

I'd be happy to explain the provided JSON data and help break down what's being tested in the benchmark.

**Benchmark Definition**

The benchmark definition is represented by two JSON objects:

1. **Script Preparation Code**: This code defines two functions: `removeProperty` and `removeProperty2`. Both functions are intended to remove a property from an object, but they differ in their implementation.
	* `self.removeProperty(property)` checks if the provided `property` is in a blacklist before removing it. The blacklist contains specific properties that should not be removed.
	* `self.removeProperty2(property)` also removes the property, but it only checks for a different set of excluded properties (`blacklistSELF`) instead of using a global blacklist.
2. **Html Preparation Code**: This section is empty in this case.

**Individual Test Cases**

The test cases are represented by an array of objects:

1. Each object defines a single benchmark definition:
	* `Benchmark Definition`: The code to be executed for each test case, which invokes either `self.removeProperty` or `self.removeProperty2` with a specific property as an argument.
	* `Test Name`: A unique identifier for the test case.

**What is being tested**

The benchmark tests the performance of removing properties from an object using two different approaches:

1. **Global Blacklist**: The first test case (`"self.removeProperty('test');"`), which uses a global blacklist to check if the property to be removed exists.
2. **Local Blacklist**: The second and third test cases (`"self.removeProperty2('test');"` and `"self.removeProperty2('undisposeProperties');"`), which use a local blacklist (`blacklistSELF`) instead of a global one.

**Pros and Cons**

**Global Blacklist (removeProperty)**

Pros:

* Easier to implement, as it only requires checking the property against a fixed list.
* Can be more efficient if the blacklist is small and well-optimized.

Cons:

* May lead to slower performance if the global blacklist becomes very large or complex.

**Local Blacklist (removeProperty2)**

Pros:

* Allows for dynamic exclusion of properties, which might be beneficial in certain scenarios.
* Could potentially be faster if the local blacklist can be optimized more efficiently than the global one.

Cons:

* More difficult to implement and optimize compared to the global blacklist approach.
* May lead to slower performance due to the additional overhead of checking against a local list.

**Other Considerations**

* The benchmark assumes that the `self` object is already defined and has the required properties and methods.
* The test cases do not account for potential edge cases, such as an empty object or a property with a value of `null`.
* The benchmark only tests the removal of individual properties; it does not evaluate the performance of the overall `removeProperty` function.

**Alternative Approaches**

Other approaches to removing properties from an object could include:

1. Using a different data structure, such as a hash table or a map, to store and manage the object's properties.
2. Implementing a more sophisticated property removal algorithm that takes into account factors like property dependencies or caching.
3. Utilizing compiler optimizations or other language features to improve performance.

Keep in mind that these alternative approaches may come with their own set of challenges and trade-offs, and might not be directly comparable to the global and local blacklist approaches used in this benchmark.
