Benchmark: IntersectionwithLodashVsCustomObjectBased

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var a = [],
    b = [],
    c = [],
    d = [],
    i;
for (i = 0; i < 1000; i++) {
    a.push(Math.floor(Math.random() * 1000) + 1);
    b.push(Math.floor(Math.random() * 1000) + 1);
  	c.push(Math.floor(Math.random() * 1000) + 1);
  	d.push(Math.floor(Math.random() * 1000) + 1);
}

Tests:

Lodash
_.intersection(a,b,c,d);
ObjectBased
var intersection = (function(){ return function(){ var len = arguments.length; var here = [...arguments]; let hashObject = {}; let returnarr=[]; for(var i=0;i<len;i++){ if(!i) here[i].forEach(num => hashObject[num] = i); else{ here[i].forEach(num=>{ if(hashObject.hasOwnProperty(num) && hashObject[num] === i-1){ hashObject[num]=i; if(i===len-1) returnarr.push(parseInt(num)) } }) } } return returnarr; } }()); intersection(a,b,c,d);

Let's break down the provided benchmark and its various components.

**Benchmark Definition JSON**

The benchmark definition JSON provides information about the benchmark, including its name, description, script preparation code, HTML preparation code (which includes a reference to Lodash), and individual test cases.

**Script Preparation Code**

The script preparation code creates four arrays (`a`, `b`, `c`, `d`) of size 1000 each, filled with random numbers between 1 and 1000. These arrays will be used as input for the benchmark's intersection function.

**HTML Preparation Code**

The HTML preparation code includes a reference to Lodash version 4.17.5, which is used in one of the test cases.

**Individual Test Cases**

There are two individual test cases:

1. **Lodash**
	* Benchmark Definition: `_.intersection(a,b,c,d);`
	* This test case uses the Lodash library to perform an intersection operation on the four arrays (`a`, `b`, `c`, `d`).
2. **ObjectBased**
	* Benchmark Definition: `var intersection = (function(){...});`
	* *This test case defines a custom object-based implementation of the intersection function, which is then called with the same input arrays as Lodash.*

**Options Compared**

The two test cases compare the performance of:

1. Using an external library (Lodash) to implement the intersection function.
2. Implementing the intersection function from scratch using a custom object-based approach.

**Pros and Cons of Each Approach**

* **Lodash:**
	+ Pros:
		- Faster execution time, as Lodash is a well-maintained and optimized library.
		- Less code to write and maintain.
	+ Cons:
		- External dependency on the Lodash library, which may affect performance or security.
		- May not be suitable for all use cases or environments where Lodash is not available or supported.
* **ObjectBased:**
	+ Pros:
		- More control over implementation details and optimization opportunities.
		- No external dependencies or potential security risks.
	+ Cons:
		- Requires more code to write and maintain, which can lead to maintenance overhead.
		- May result in slower execution times due to the custom implementation.

**Other Considerations**

* The benchmark uses a Windows-specific browser (Chrome 83) to execute the tests. Other platforms or browsers may yield different results.
* The test cases use arrays as input data, but other data structures or inputs (e.g., objects, numbers, etc.) may be used in real-world scenarios.

**Alternatives**

Other alternatives for implementing an intersection function include:

1. Using built-in array methods like `filter()` and `reduce()`.
2. Implementing a custom algorithm using bitwise operations.
3. Utilizing other libraries or frameworks that provide similar functionality (e.g., `d3` for data analysis).

Keep in mind that the choice of implementation depends on the specific requirements, performance constraints, and personal preference of the developer.
