Benchmark: Find Object by Label

Script Preparation code:

var objectToFind = {
  mappings: {
		'page.view': {
			event: 'trackPageLoad',
			't3': {
				key1: '',
				key2: '',
				key3: '',
				key4: '',
				key5: ''
			}
		},
		'link.generic': {
			event: 'imaplaceholdertest',
			'imaplaceholdertest-weird-name': {
				fillerItem: 'potato'
			}
		}
	},
	sendData: {
		gtm: 'pushToGTMDataLayer'	
	}
};

function findObjectByLabel(obj, label) {
  for(var elements in obj){
    if (elements === label){
      console.log(obj[elements]);
    }
    if(typeof obj[elements] === 'object'){
      findObjectByLabel(obj[elements], 'jssType');
    }

  }
};

function findObjectByLabelProperty(obj, label) {
	obj.hasOwnProperty(label);
};

**What is tested on the provided JSON?**

The provided JSON represents two JavaScript microbenchmarks:

1. `findObjectByLabel(objectToFind, 'page.view')`: This benchmark tests the performance of finding an object by its label in a nested object structure. The `objectToFind` variable contains a complex object with multiple levels of nesting and various properties.
2. `findObjectByLabelProperty(objectToFind, 'page.view')`: This benchmark tests the performance of using the `hasOwnProperty` method to check if a property exists on an object.

**Options compared**

The benchmarks compare two approaches:

1. **Recursive search**: The first benchmark uses a recursive function `findObjectByLabel` to search for the desired object by label.
2. **Property existence check**: The second benchmark uses the `hasOwnProperty` method to check if a property exists on an object.

**Pros and cons of each approach**

**Recursive search (findObjectByLabel)**

Pros:

* Can handle complex object structures with nested objects
* Allows for flexible searching based on various properties

Cons:

* May lead to performance issues due to excessive function calls and potential stack overflow errors if the object structure is too deep
* Can be slower than property existence checks due to the overhead of recursive function calls

**Property existence check (hasOwnProperty)**

Pros:

* Fast and efficient method for checking property existence
* Avoids potential stack overflow errors associated with recursive functions

Cons:

* Limited to checking if a single property exists on an object
* May not be suitable for complex object structures or nested objects

**Other considerations**

The benchmarks also consider the use of libraries, such as Google Tag Manager (GTM), which is used in the `sendData` variable. Additionally, the benchmarks may test other aspects of JavaScript performance, such as string processing or array operations.

In the provided benchmark result, Chrome 93 is shown to be slightly faster for both tests than its predecessor version.

**Alternatives**

Other alternatives to these approaches could include:

* Using a different data structure, such as an array or a Map, instead of objects
* Implementing a more efficient search algorithm, such as binary search or hashing
* Utilizing JavaScript features like `for...in` loops or the `Object.keys()` method for iterating over object properties
