Benchmark: Boolean constructor vs double negotiation trick in javascript 3

Script Preparation code:

var bFalse = false;
var sEmpty = '';
var sFilled = 'Foo';
var nZero = 0;
var nOne = 1;

AخA
 
var bFalse = false;var sEmpty = '';var sFilled = 'Foo';var nZero = 0;var nOne = 1;

Tests:

Boolean
Boolean(bFalse) Boolean(sEmpty) Boolean(sFilled) Boolean(nZero) Boolean(nOne)
Boolean(bFalse)
Boolean(sEmpty)
Boolean(sFilled)
Boolean(nZero)
Boolean(nOne)
double neg with booleans
!Boolean(bFalse) !Boolean(sEmpty) !Boolean(sFilled) !Boolean(nZero) !Boolean(nOne)
!Boolean(bFalse)
!Boolean(sEmpty)
!Boolean(sFilled)
!Boolean(nZero)
!Boolean(nOne)
Short case
Boolean(bFalse)
Boolean(bFalse)

What is being tested?

MeasureThat.net is testing two different approaches for creating Boolean values in JavaScript:

Boolean constructor: Creating a new Boolean value using the Boolean() function, e.g., Boolean(bFalse).
Double negation trick: Using double negation to create a Boolean value, e.g., !Boolean(bFalse).

The benchmark is testing these two approaches with different inputs:

Empty strings (sEmpty)
Non-empty strings (sFilled = 'Foo')
Numbers (0 and 1)

Options compared

The two options being compared are:

Option 1: Using the Boolean constructor (Boolean() function)
Option 2: Double negation trick (! operator followed by Boolean())

LLMs can make mistakes. Check important info.
