@@rithmschool :) Coming to my mind right now would be a comparison of the operators nullish coalescing vs. logical OR vs. logical AND ?? || && When (not) to use them, best practices, etc.

The Video is really helpful but now I feel so confused because I've just learnt about short-circuitng isn't grad.location.city || "your city " supposed to evaluate to "your city " . I'm of the view that grad.location.city is undefined therefore the string is the only truthy value .
