The Math.SQRT2 static data property represents the square root of 2, approximately 1.414.
function getRoot2() {
return Math.SQRT2;
}
console.log(getRoot2());
// Expected output: 1.4142135623730951
Math.SQRT2 is a constant and a more performant equivalent to Math.sqrt(2).
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
