The call to `alert` does not return a value. Or, in other words, it returns `undefined`.

Apelul către `alert` nu returnează o valoare. Sau, prin alte cuvinte, returnează `undefined`.

1. The first OR `||` evaluates its left operand `alert(1)`. That shows the first message with `1`.
10-
2. The `alert` returns `undefined`, so OR goes on to the second operand searching for a truthy value.
11-
3. The second operand `2` is truthy, so the execution is halted, `2` is returned and then shown by the outer alert.
9+
1. Primul OR `||` evaluează operantul din stânga sa `alert(1)`. Aceasta afișează primul mesaj cu `1`.

2. `alert` întoarce `undefined`, așa că OR merge la al doilea operand căutând o valoare truthy.

3. Cel de al doilea operand `2` este truthy, așa că execuția este oprită, `2` este returnat fiind afișat de către `alert`-ul exterior.

There will be no `3`, because the evaluation does not reach `alert(3)`.
13+
`3` nu va fi afișat, deoarece evaluarea nu ajunge la `alert(3)`.

The call to `alert` returns `undefined` (it just shows a message, so there's no meaningful return).

Because of that, `&&` evaluates the left operand (outputs `1`), and immediately stops, because `undefined` is a falsy value. And `&&` looks for a falsy value and returns it, so it's done.

Apelul către `alert` întoarce `undefined` (afișează doar un mesaj, deci nu întoarce nimic semnificativ).

Din cauza aceasta, `&&` evaluează operantul din stânga (output-ul `1`), și se oprește imediat, deoarece `undefined` este o valoare falsy. Iar `&&` caută o valoare falsy și o întoarce, deci a terminat.

The precedence of AND `&&` is higher than `||`, so it executes first.
