What does the program print?

JavaScript

let out = "";
for (let i = 1; i <= 10; i++) {
    if (i % 2 === 0) {
        continue;
    }
    if (i > 7) {
        break;
    }
    out += i;
}
console.log(out);

1357

Expecting 13579: break leaves the whole loop, not just the if braces. At i = 9 the loop ends, so 9 is never added.
Expecting 1: continue does not end the loop. It skips the rest of this iteration and goes on with the next i, so every odd number up to 7 gets added.

What does the program print if the two if blocks swap places?
What does the program print if out starts as 0 instead of ""?
