Description

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).

Examples

Using Math.SQRT2

The following function returns the square root of 2:

function getRoot2() {
  return Math.SQRT2;
}

getRoot2(); // 1.4142135623730951
