Javascript to convert degrees, to decimal, and UTM

I´m trying to convert Degrees, Minutes and Seconds, to decimal degrees, and finally to UTM. Is there any example or library available for this purpose?

Thanks!

There are some useful libraries for doing this kind of thing, in particular geolib and utm-latlng.

Once we import these we can convert from Degrees, Minutes, Seconds with geolib and then to UTM with utm-latlng: 

const geolib = require("geolib");
const UTM = require("utm-latlng");
const utm = new UTM();

const input = { lat: "34° 3′ 12.96″ N", lon: "118° 14′ 34.8″ W" };
const decimalCoords = geolib.toDecimal(input);

console.log("Input:", input);
console.log("Degrees/Minutes/Seconds To Decimal:", decimalCoords);
console.log("UTM:", utm.convertLatLngToUtm(decimalCoords.lat, decimalCoords.lon, 0));
