It seems to me that that is precisely what the void operator is for.
But I would think the following is easier to understand and therefore
more maintainable:
function sample(callback) {
if (cond) {
callback();
} else {
// do other stuff
// return some value?
}
// implied return undefined;
}
or
function sample(callback) {
if (!cond) {
// do other stuff
// return some value?
}
callback();
}
