Benchmark: json stringify vs string...

Script Preparation code:

function makeTestData() { return { name: "Matheus de Sousa Martins", age: 30, phone: "999999999999" }; }

Tests:

toString
`{ name: "Matheus de Sousa Martins", age: 30, phone: "999999999999" }`
JSON.stringify
JSON.stringify(makeTestData());

Let's dive into the world of JavaScript microbenchmarks and explore what's being tested on MeasureThat.net.

**Benchmark Definition**

The benchmark is defined by a JSON object that contains two main pieces of information:

1. **Script Preparation Code**: This code snippet defines a function `makeTestData()` that returns an object with three properties: `name`, `age`, and `phone`. This function will be used to generate test data for the benchmark.
2. **Html Preparation Code**: Unfortunately, this field is empty, which means that no HTML preparation code is required for this benchmark.

**Individual Test Cases**

The benchmark consists of two individual test cases:

1. **`toString`**: In this test case, a string representation of an object is obtained by calling the `toString()` method on the object.
2. **`JSON.stringify`**: In this test case, the `JSON.stringify()` function is called with the result of `makeTestData()` as its argument.

**Options Compared**

In this benchmark, two options are being compared:

1. **`toString()`**: This option uses a built-in JavaScript method to convert an object to a string.
2. **`JSON.stringify()`**: This option uses a built-in JavaScript function to serialize an object into a JSON-formatted string.

**Pros and Cons of Each Approach**

Here's a brief summary of the pros and cons of each approach:

* `toString()`: Pros:
	+ Lightweight and fast
	+ Works with any type of object (not just JSON objects)
Cons:
	+ May not be as readable or human-friendly as JSON output
* `JSON.stringify()`:
	+ Pros:
		- Human-readable and easy to understand
		- Can handle complex data structures like arrays and objects
	+ Cons:
		- May be slower than `toString()`
		- Requires an additional library (in this case, the built-in `JSON` object)

**Library Used**

In this benchmark, the `JSON` object is used to serialize an object into a JSON-formatted string. The `JSON.stringify()` function is a built-in JavaScript method that takes an object as its argument and returns a JSON-formatted string.

**Special JS Feature or Syntax**

There are no special JavaScript features or syntaxes being tested in this benchmark. Both options use standard JavaScript methods and functions to achieve their results.

**Other Alternatives**

If you wanted to compare these two options, you could also consider using other serialization formats like:

* `Stringify()` from the Lodash library
* `YAML` or `XML` serialization libraries
* Custom serialization algorithms

However, for most use cases, `toString()` and `JSON.stringify()` are sufficient and efficient ways to convert objects to strings.
