Answer 1

You can use the length of the returned DOM elements as a falsy and throw a new error like so:

var el = '#el';

if ($(el).length){
    // Do Stuff
} else {
    throw new Error("Element "+el+" Doesn't Exist");
}

OR

// Ignores Empty Selector
if ($('#el').length){
    // Do Stuff
}

I hope this helps!
