If you have dynamic classes or don't know what classes could be already applied then this method I believe is the best approach:

// addClass
$('path').attr('class', function(index, classNames) {
    return classNames + ' class-name';
});

// removeClass
$('path').attr('class', function(index, classNames) {
    return classNames.replace('class-name', '');
});
