The Math.LN2 static data property represents the natural logarithm of 2, approximately 0.693:
function getNatLog2() {
return Math.LN2;
}
console.log(getNatLog2());
// Expected output: 0.6931471805599453

Because LN2 is a static property of Math, you always use it as Math.LN2, rather than as a property of a Math object you created (Math is not a constructor).
The following function returns the natural log of 2:
function getNatLog2() {
return Math.LN2;
}
getNatLog2(); // 0.6931471805599453
