Benchmark: Compare number vs compare string

Script Preparation code:

var numShort1 = 2**32;
var numShort2 = 2**32;
var numShort3 = 2**31;
var numLong1 = 2**256;
var numLong2 = 2**256;
var numLong3 = 2**255;
var stringShort1 = "test";
var stringShort2 = "test";
var stringShort3 = "t35t";
var stringLong1 = "cyclonicBarrierTechnology";
var stringLong2 = "cyclonicBarrierTechnology";
var stringLong3 = "cockAndBallTorture";

Tests:

Short Number
console.log(numShort1 == numShort3 || numShort1 == numShort2);
Long Number
console.log(numLong1 == numLong3 || numLong1 == numLong2);
Short String
console.log(stringShort1 == stringShort3 || stringShort1 == stringShort2);
Long String
console.log(stringLong1 == stringLong3 || stringLong1 == stringLong2);

**Benchmark Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The provided benchmark compares the speed of comparing numbers vs comparing strings in JavaScript.

**Test Cases**

The test cases are individual comparisons using different data types: numbers (short and long) and strings (short and long). Each test case uses a specific comparison operator (`==` or `||`) to evaluate whether two values are equal.

**Options Compared**

The benchmark compares the following options:

1. **Short Number Comparison**: Comparing two short integers (16-bit signed).
2. **Long Number Comparison**: Comparing two long integers (32-bit signed).
3. **Short String Comparison**: Comparing two short strings.
4. **Long String Comparison**: Comparing two long strings.

**Pros and Cons**

* **Faster Operations**: Comparing numbers is generally faster than comparing strings, as it involves simple arithmetic operations versus string comparisons that require searching for matches.
* **Less CPU Usage**: Comparing numbers requires less CPU usage compared to comparing strings, especially for longer strings.
* **More Robust Results**: Number comparisons are more robust and less prone to edge cases like null or undefined values.

However, there are also some potential drawbacks:

* **Less Accurate Results**: String comparisons can produce different results due to factors like Unicode encoding and character set differences.
* **More Variable Performance**: String comparison performance can be affected by the specific characters used in the strings being compared.

**Libraries Used**

None of the provided benchmark test cases use any external libraries. However, it's worth noting that some JavaScript engines might have built-in optimizations or features that could affect the results of these comparisons.

**Special JS Features or Syntax**

The benchmark does not explicitly mention any special JavaScript features or syntax being used beyond the basic comparison operators (`==` and `||`).
