我正在尝试将功能转换为箭头功能，但无法正常工作。我在做一些错误吗，我的代码在下面。请引导我在哪里做错。
// Call Back Function
function ask(question, yes, no) {
if (confirm(question)){
yes()
}
else {
no()
}
}
function showOk() {
console.log("you agreed")
}
function showCancel() {
console.log("canceled")
}
ask("do you agree ?", showOk, showCancel)
Arrow Function
let ask = (question, yes, no) => {if (confirm(question)) {
yes()
} else {
no()
}
let showOk = () => console.log("you agreed");
let showCancel = () => console.log("Canceled");
}
ask("do you agree ?", showOk, showCancel)
For an arrow function to have an implicit return expression is required, so for each function, you have to return something, at least
return true.您的代码看起来像
您有一个花括号来晚了。
一种较短的方法是将这些函数与条件语句一起使用。
