javascript - 从 JS 中导入的模块内部触发本地函数

Question

我正在尝试运行本地函数，但我想从导入的模块内部触发它。这将是它应该如何工作的草图......有什么建议吗？

index.js

import { runBar } from "myModule.js";

runBar();

function foo() {
    console.log('foo should run whenever bar is executed');
}

myModule.js

export function runBar(){
   bar();
}

function bar() {
    console.log("bar is running...");
    //I want to call foo from here...
}

将 foo 作为参数传递怎么样？

index.js

import { runBar } from "myModule.js";

runBar(foo);

function foo() {
    console.log('foo should run whenever bar is executed');
}

myModule.js

export function runBar(foo){
   bar(foo);
}

function bar(foo) {
    console.log("bar is running...");
    //I want to call foo from here...
    foo();
}
