Math.SQRT2

The Math.SQRT2 property represents the square root of 2, approximately 1.414:

$$\mathtt{\mi{Math.SQRT2}} = \sqrt{2} \approx 1.414$$

Because SQRT2 is a static property of Math, you always use it as Math.SQRT2, rather than as a property of a Math object you created (Math is not a constructor).

The following function returns the square root of 2:

function getRoot2() {
  return Math.SQRT2;
}

getRoot2(); // 1.4142135623730951
