Benchmark: JSON stringify - MeasureThat.net

Tests:

JSON stringify
const testObject = {gameName: 'lotto', maxPrimaryLineLength: 6, maxSecondaryLineLength: 0,currentPrimaryLine: [1,2,3,4,5],currentSecondaryLine: []} const testObject2 = {gameName: 'lotto', maxPrimaryLineLength: 6, maxSecondaryLineLength: 0,currentPrimaryLine: [1,2,3,4,5],currentSecondaryLine: []} console.log(JSON.stringify(testObject));
JSON stringify equality
const testObject = {gameName: 'lotto', maxPrimaryLineLength: 6, maxSecondaryLineLength: 0,currentPrimaryLine: [1,2,3,4,5],currentSecondaryLine: []} const testObject2 = {gameName: 'lotto', maxPrimaryLineLength: 6, maxSecondaryLineLength: 0,currentPrimaryLine: [1,2,3,4,5],currentSecondaryLine: []} console.log(JSON.stringify(testObject) === JSON.stringify(testObject2));

Let's dive into the world of JavaScript microbenchmarks.

**What is being tested?**

The provided JSON represents two test cases for measuring the performance of the `JSON.stringify()` function in JavaScript. The tests compare two identical objects (`testObject` and `testObject2`) to see how quickly each browser can execute a simple equality check using `JSON.stringify()`. In essence, the goal is to measure the time taken by each browser to serialize the same data twice.

**Options compared:**

The benchmark compares two options:

1. **Serialization**: The original code that serializes the object using `JSON.stringify()` and logs it to the console.
2. **Equality check**: A modified version of the original code that checks if the serialized string is equal to another identical string (i.e., `testObject2`).

**Pros and Cons:**

1. **Serialization**: This approach tests the performance of serializing a JavaScript object to a string, which can be useful for data storage or transmission.
	* Pros:
		+ Relevant for use cases where data needs to be serialized and sent over networks.
		+ Can help identify issues with object serialization.
	* Cons:
		+ May not be the most representative benchmark for JavaScript performance, as it only tests serialization.
2. **Equality check**: This approach tests the performance of comparing two identical strings using `JSON.stringify()`.
	* Pros:
		+ Relevant for use cases where data needs to be compared for equality.
		+ Can help identify issues with string comparison in JavaScript.
	* Cons:
		+ May not accurately represent real-world usage scenarios, as it only tests equality checking.

**Library and purpose:**

None of the test code uses a library explicitly. However, `JSON.stringify()` is a built-in JavaScript function that converts an object to a JSON string.

**Special JS feature or syntax:**

There are no special JavaScript features or syntax used in this benchmark.

**Other alternatives:**

Alternative approaches could include:

* Testing the performance of other serialization libraries (e.g., Lodash's `serializeObject()`).
* Comparing the performance of different equality check algorithms (e.g., using a custom function to compare objects).
* Adding more complex test cases, such as testing with large datasets or nested objects.

However, these alternatives would require modifying the existing benchmark code and may not be directly relevant to measuring the performance of `JSON.stringify()`.
