The Math.SQRT1_2 static data property represents the square root of 1/2, which is approximately 0.707.
function getRoot1Over2() {
return Math.SQRT1_2;
}
console.log(getRoot1Over2());
// Expected output: 0.7071067811865476
Math.SQRT1_2 is a constant and a more performant equivalent to Math.sqrt(0.5).
Because SQRT1_2 is a static property of Math, you always use it as Math.SQRT1_2, rather than as a property of a Math object you created (Math is not a constructor).
The following function returns 1 over the square root of 2:
function getRoot1_2() {
return Math.SQRT1_2;
}
getRoot1_2(); // 0.7071067811865476
