Try it

function getNatLog10() {
  return Math.LN10;
}

console.log(getNatLog10());
// Expected output: 2.302585092994046

Description

Because LN10 is a static property of Math, you always use it as Math.LN10, rather than as a property of a Math object you created (Math is not a constructor).

Examples

Using Math.LN10

The following function returns the natural log of 10:

js
function getNatLog10() {
  return Math.LN10;
}

getNatLog10(); // 2.302585092994046
