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:

js

function getNatLog2() { return Math.LN2; } getNatLog2(); // 0.6931471805599453
