Converting Youtube Data API V3 video duration format to seconds in JavaScript/Node.js

Question

I\'m trying to convert ISO 8601 string to seconds in JS/Node. The best I could come up with was:

function convert_time(duration) {
    var a = duration.match

Here's my solution:

function parseDuration(duration) {
    var matches = duration.match(/[0-9]+[HMS]/g);

    var seconds = 0;

    matches.forEach(function (part) {
        var unit = part.charAt(part.length-1);
        var amount = parseInt(part.slice(0,-1));

        switch (unit) {
            case 'H':
                seconds += amount*60*60;
                break;
            case 'M':
                seconds += amount*60;
                break;
            case 'S':
                seconds += amount;
                break;
            default:
                // noop
        }
    });

    return seconds;
}
