Node JS -如何获取函数外部的值？

let globalValue = 'I am outside the function';

function printGlobalValue() {
    console.log(globalValue); // 输出: I am outside the function
}

printGlobalValue();

function outerFunction() {
    let outerValue = 'I am from outer function';

    function innerFunction() {
        console.log(outerValue); // 输出: I am from outer function
    }

    return innerFunction;
}

const innerFunc = outerFunction();
innerFunc();

let externalValue = 'I am an external value';

function printValue(value) {
    console.log(value); // 输出: I am an external value
}

printValue(externalValue);

// module.js
module.exports = {
    externalValue: 'I am an external value'
};

// main.js
const { externalValue } = require('./module');

function printValue() {
    console.log(externalValue); // 输出: I am an external value
}

printValue();
