Benchmark: to string methods

Tests:

toString
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(String(num)); }
String
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(num.toString()); }
Template
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(`${num}`); }

Measuring the performance of different approaches to converting numbers to strings is an interesting benchmark.

**What is being tested?**

The provided JSON represents three test cases, each with its own script that converts the number 500 to string using different methods:

1. **toString**: The built-in `String()` function.
2. **String**: The dot notation (`num.toString()`) used to access a property on an object (in this case, the number itself).
3. **Template**: The template literal syntax (``${num}``).

**Options compared**

The three options being compared are:

1. **toString**: A built-in function that converts a value to a string.
2. **String**: An expression that uses dot notation to access a property on an object (in this case, the number itself).
3. **Template**: A syntax for creating strings with embedded expressions.

**Pros and Cons**

Here's a brief summary of each approach:

1. **toString**:
	* Pros: Fast, efficient, and widely supported.
	* Cons: May not work as expected if used in certain contexts (e.g., when the `String()` function is called on an object with no own properties).
2. **String**:
	* Pros: Can be useful for accessing properties on objects using dot notation.
	* Cons: Slower than `toString` and may have performance implications if used frequently.
3. **Template**:
	* Pros: Provides a convenient way to embed expressions in strings, making it easy to create dynamic content.
	* Cons: May introduce additional overhead due to the creation of an intermediate string object.

**Library and purpose**

None of the test cases use any external libraries.

**Special JS feature or syntax**

The template literal syntax (``${num}``) is used in one of the test cases. Template literals were introduced in ECMAScript 2015 (ES6) as a way to create strings with embedded expressions using backticks (`). They allow you to insert values into a string using the `${expression}` syntax.

**Other alternatives**

In addition to the three options being tested, other approaches could be explored:

* Using `Number.toString()` or `String.prototype.valueOf()`
* Using a custom function to convert numbers to strings
* Using a different data structure, such as an array of strings, to store the result

It's worth noting that the test cases only focus on converting a single number (500) to string using the provided methods. In practice, you may want to explore more complex scenarios or edge cases when optimizing performance or implementing conversion functions.
