Please note the `if` check in lines `(*)` and `(**)`. Every browser except Safari returns `null` when the input is canceled, and Safari returns an empty string. So we must treat them same for compatibility.
Also note the vertical indents inside the `if` blocks. They are technically not required, but make the code more readable.
