let yourName;do {  yourName = prompt("Who are you?");} while (!yourName);console.log(yourName);此代碼在在線教科書中給出：https ://eloquentjavascript.net/02_program_struct.html我還嘗試以這種方式在控制臺中運行它：let funGame;do {     funGame = prompt("enter anything to get rid of this Game");} while (!funGame); console.log(funGame);我正在使用谷歌瀏覽器來測試這段代碼。此代碼僅運行一次，而它應該無限期地運行，直到提供空字符串為止。
