JavaScript's `Math.PI`

constant can be used to convert an angle from degrees to radians. The conversion formula is `radians = degrees * Math.PI / 180.0`

.

const degreesToRads = deg => (deg * Math.PI) / 180.0;
degreesToRads(90.0);

Radians to degrees

Conversely, the conversion formula from radians to degrees is `degrees = radians * 180.0 / Math.PI`

.

const radsToDegrees = rad => (rad * 180.0) / Math.PI;
radsToDegrees(Math.PI / 2);
