Degrees To Decimal With Javascript Reworked

Two years ago I was pretty happy with this little piece of code to transform degrees to the decimal value. Yesterday, I found a neater way to do the same:

let deg = [50, 30, 0];

function degToDec(prev, cur, curIndex) {
    return prev + cur / Math.pow(60, curIndex);
}

deg.reduce(degToDec);

Once you have an input array, that’s pretty much it. Love JavaScript.
