Question

由于某种原因，计算机不在乎registeredEarly变量，我需要它来运行else if代码，但实际上并不需要。我也仔细检查了语法。请帮忙！

我尝试更改布尔值以提供预期的结果，但无济于事。

let raceNumber = Math.floor(Math.random() * 1000);

const registeredEarly = false;

let runnerAge = 19;

if (runnerAge => 18 && registeredEarly === true) {
  raceNumber += 1000;
} else if (runnerAge => 18 && registeredEarly === false) {
    raceNumber += 1000;
}

if (runnerAge => 18 && registeredEarly === true) {
  console.log(`Your race begins at 9.30am, your race number is ${raceNumber}.`);
} else if (runnerAge => 18 && registeredEarly === false) {
    console.log(`Your race begins at 11.00am, your race number is ${raceNumber}.`);
}

我希望结果是“您的比赛从11:00 am开始，您的比赛号码为（raceNumber）。”但是我得到的是“您的比赛从上午9.30开始，您的比赛号码是（raceNumber）。”为什么会这样？

if (runnerAge => 18 && registeredEarly === true) {
  raceNumber += 1000;
} else if (runnerAge => 18 && registeredEarly === false) {
    raceNumber += 1000;
}
if (runnerAge => 18 && registeredEarly === true) {
  console.log(`Your race begins at 9.30am, your race number is ${raceNumber}.`);
} else if (runnerAge => 18 && registeredEarly === false) {
    console.log(`Your race begins at 11.00am, your race number is ${raceNumber}.`);

您应将=>更改为> =

如果语句正确运行，为什么不这样做呢？
