javascript - 如何在javascript中的do-while循环中嵌套if语句

Question

var temp = 110;
for {
    temp-=1
    if (temp >= 90) {
        console.log("Today's temperature is "+temp+"! "+"Lets go play ball")
    } else {
        console.log("Today's temperature is "+temp+"! "+"It is too hot today to ball!")
    }
    
}while (temp > 90)

请查看我的代码片段。由于某种原因它不会运行，并指出一些括号错误，因为我已经检查了括号。

它的做不是为了

var temp = 110;
do { //its `do` not `for`
  temp -= 1;
  if (temp >= 90) {
    console.log("Today's temperature is " + temp + "! " + "Lets go play ball")
  } else {
    console.log("Today's temperature is " + temp + "! " + "It is too hot today to ball!")
  }

} while (temp > 90);

您可以使用prompt()进行用户输入:

var temp = prompt('Input temperature', '110'); // (message, default input)
console.log('temp', temp);
do { //its `do` not `for`
  temp -= 1;
  if (temp >= 90) {
    console.log("Today's temperature is " + temp + "! " + "Lets go play ball")
  } else {
    console.log("Today's temperature is " + temp + "! " + "It is too hot today to ball!")
  }

} while (temp > 90);
