Benchmark: приведения к числу и строке в или выражении 3

Script Preparation code:

const idS = '11';
const idN = 11;

Tests:

idS === idN || idS === String(idN) || Number(idS) === idN
const idS = '11'; const idN = 11; const res = idS === idN || idS === String(idN) || Number(idS) === idN
idS === idN || idS === Number(idN) || String(idS) === idN
const idS = '11'; const idN = 11; const res = idS === idN || idS === Number(idN) || String(idS) === idN
idS === idN
const idS = '11'; const idN = 11; const res = idS === idN

Let's break down the provided benchmark and its options.

**Benchmark Overview**

The benchmark measures how fast JavaScript code can compare strings to numbers. It uses two types of data: string literals (`'11'`) and numeric literals (`11`).

**Options Compared**

There are three options compared in the benchmark:

1. `idS === idN`: Directly comparing a string literal with a numeric literal.
2. `idS === String(idN)`: Converting the numeric literal to a string using the `String()` function and then comparing it with the original string literal.
3. `Number(idS) === idN`: Attempting to convert the string literal to a number using the `Number()` function and then comparing it with the original numeric literal.

**Pros and Cons of Each Option**

1. **Direct Comparison (`idS === idN`)**:
	* Pros: Simple, efficient, and fast.
	* Cons: May not work as expected if the string literal cannot be converted to a number (e.g., if it contains non-numeric characters).
2. **String Conversion (`idS === String(idN)`)**:
	* Pros: Works even if the string literal cannot be converted to a number, since `String()` will return the original string.
	* Cons: May be slower than direct comparison due to the additional function call.
3. **Number Conversion (`Number(idS) === idN`)**:
	* Pros: Can handle numeric literals that contain non-numeric characters or special values (e.g., NaN, Infinity).
	* Cons: May fail if the string literal cannot be converted to a number (e.g., if it contains non-numeric characters).

**Library and Special JavaScript Features**

There are no libraries used in this benchmark. However, some special JavaScript features may be implicitly used, such as:

* String conversion (`String()`) and number conversion (`Number()`), which are built-in functions.
* Template literals (not explicitly mentioned but implied by the use of string literals).

**Other Alternatives**

If you wanted to add more options to the benchmark, you could consider comparing strings using different encoding schemes (e.g., UTF-8) or using regular expressions.

Additionally, if you wanted to measure performance in a more general sense, you could consider adding benchmarks for:

* String comparison with string literals only
* Number comparison with numeric literals only
* Converting numbers to strings and vice versa

Keep in mind that these alternatives would require additional modifications to the benchmark definition and test cases.
