执行以下代码时出错:
let myFunc4 = (nameFunction) => ("Hello " + nameFunction() + ".");
let printName = (nameFunction, printFunction) => printFunction(myFunc4(nameFunction));
printName(function () { return "Adam" }, console.log);
它应该返回“Hello Adam”,但是我收到以下错误:
Error: (SystemJS) Illegal invocation TypeError: Illegal invocation at printName
我发现很难在花费大量时间查看控制台日志后发现问题所在。

这很好。请运行摘要。您正在节点中运行吗?如果是这样,请将其更新为最新版本。
let myFunc4 = (nameFunction) => ("Hello " + nameFunction() + ".");
let printName = (nameFunction, printFunction) => printFunction(myFunc4(nameFunction));
printName(function() {
return "Adam"
}, console.log);
